Why Do We Receive Calls from Call Centers?

Call center calls are a daily reality for many of us. But why do we receive so many unwanted calls? The reasons are diverse and vary depending on the companies and their goals.

Acquisition of New Customers and Sale of Products/Services

One of the main reasons call centers call us is to acquire new customers and sell products or services. Companies use telemarketing as a strategy to reach a vast audience and promote their offers. Often, these calls are targeted at people who might be interested in what the company proposes, but sometimes they can also be random and indiscriminate.

Surveys and Market Research

Some call centers call us to conduct surveys and market research. These calls can be useful for companies to gather information on consumer preferences, test new products, or evaluate customer satisfaction. However, they can also be annoying and intrusive, especially if received frequently.

Debt Collection and Information

In some cases, call centers call us to collect debts or to obtain information about us. These calls can come from banks, financial institutions, or other companies with whom we have a business relationship. Although they may be legitimate, it is important to be cautious and verify the caller’s identity before providing personal or financial information.

Unfair and Abusive Practices

Unfortunately, some call centers use unfair and abusive practices. For example, they may purchase lists of numbers from third parties without our consent, violating our privacy. They may also use robocall systems that send pre-recorded messages without the possibility of speaking to an operator. These practices are often illegal and can be reported to the competent authorities.

If you are tired of constant unwanted calls from call centers, the Public Register of Oppositions (RPO) is your first ally. It is a free service established by the Ministry of Economic Development that allows you to object to the use of your phone number for telemarketing purposes.

By signing up for the RPO, you exercise your right to object to telemarketing and drastically reduce the number of unwanted calls you receive. Registration is simple and can be done online, by phone, or by mail.

How to Sign Up for the Public Register of Oppositions

Signing up for the RPO is quick and easy. You can do it in three ways:

  1. Online: Fill out the registration form on the official website of the Public Register of Oppositions: https://registrodelleopposizioni.it/
  2. By phone: Call the toll-free number 800 957 766 from a landline, or 06 42986411 for mobile phones.
  3. By email: fill out the citizen registration form and send it completed to iscrizione@registrodelleopposizioni.it. Subsequently, you will have to demonstrate the availability of the indicated numbers by making a call from the same numbers to an RPO telephone number that will be communicated to you via email.

Remember to have your personal data and the phone number you want to register at hand.

Timeframes and Limits of the Public Register of Oppositions

Registration in the Public Register of Oppositions becomes effective within 15 days of the request. However, it is important to know that the RPO does not block all unwanted calls.

The Public Register of Oppositions does not block:

  • Calls from companies with whom you have an ongoing contractual relationship or one concluded less than 30 days ago.
  • Calls for charitable purposes or research without sales purposes.
  • Calls from political parties or trade unions.
  • Calls made with your explicit consent.

Despite these limits, signing up for the RPO is a fundamental step to protect your privacy and significantly reduce unwanted calls.

Blocking Phone Numbers Individually

A practical guide explains how to permanently block unwanted calls.

If you receive unwanted calls from specific numbers, you can block them directly on your phone, whether it is a mobile or landline. This method is particularly useful if the calls come from numbers that are not registered in the Public Register of Oppositions list.

Blocking Phone Numbers on Mobile

Most modern smartphones offer the ability to block unwanted phone numbers. The procedure may vary slightly depending on the operating system and phone model, but in general, here is how to do it:

  • Android: Open the “Phone” app, go to call history, select the number you want to block, and tap “Block/Report as spam”.
  • iOS: Open the “Phone” app, go to call history, tap the “i” icon next to the number you want to block, and select “Block this Caller”.

Some Android and iOS phones may have additional options to automatically block unknown or suspicious numbers. Check your phone’s manual or the manufacturer’s website for specific instructions.

Blocking Phone Numbers on Landline

Blocking a phone number on a landline can be a bit more complicated, as not all models offer this feature. However, there are some options you can try:

  • Call blocking function: Some modern landlines have a built-in feature to block unwanted numbers. Check your phone’s manual to see if this feature is available and how to use it.
  • Call blocking services: Many telephone operators offer paid services to block unwanted calls. Contact your operator for information on available options and costs.
  • Phones with built-in call blocking: If you are thinking of buying a new landline phone, consider a model with built-in call blocking. This feature will allow you to easily block unwanted numbers without having to resort to additional services.

Personal Blacklist

Another option, for both mobile and landline phones, is to create your own personal blacklist. You can write down unwanted numbers on a piece of paper or in a digital file and check this list every time you receive a call. If the number is on your blacklist, you already know it is an unwanted call and can decide not to answer.

Apps and Services to Block Unwanted Calls

In addition to manual blocking options and signing up for the Public Register of Oppositions, there are numerous apps and services designed specifically to help you fight unwanted calls. These solutions use advanced technologies such as spam filtering, caller identification, and shared blacklists to protect you from call centers and phone scams.

Truecaller

  • Caller Identification: Shows the caller’s name and photo, even if they are not in your address book.
  • Automatic Spam Blocking: Automatically blocks calls from numbers known to be spam or scams.
  • Personal Blacklist: Allows you to create your own list of numbers to block.
  • Call Recording: Records incoming and outgoing calls (paid feature).

Truecaller is available for free for Android and iOS, but also offers a premium version with additional features.

Should I Answer?

Should I Answer? is a simple but effective app that helps you decide whether or not to answer a call. It uses a database of numbers reported as spam or scams to evaluate the caller’s reputation and show you a warning on the screen.

Should I Answer? is available for free for Android and iOS.

Hiya

Hiya is another popular app for blocking unwanted calls. It offers features similar to Truecaller, such as caller identification, automatic spam blocking, and personal blacklist. Hiya is available for free for Android and iOS.

What to Do if Calls Continue

You followed all the advice, signed up for the Public Register of Oppositions, blocked nuisance numbers, and installed an app to filter calls, but unwanted calls keep coming? Don’t give up! There are still some actions you can take to defend yourself.

Report to the Privacy Guarantor

If you receive unwanted calls from companies that do not respect the registration in the Public Register of Oppositions or that use unfair practices, you can report the fact to the Data Protection Authority (Privacy Guarantor).

The Guarantor is the Italian authority responsible for privacy protection and can intervene by sanctioning companies that violate regulations. To report an unwanted call, you can fill out the online form available on the Guarantor’s website or send a written report.

Report Phone Scams

If you suspect you are a victim of a phone scam, it is important to report the incident to the competent authorities. Phone scams can take various forms, such as phishing, vishing, and smishing.

If you have provided personal or financial data to a scammer, contact your bank or the financial institution involved immediately and follow their instructions. Furthermore, you can file a complaint with law enforcement (State Police, Carabinieri, or Financial Guard).

Other Useful Tips

Here are some additional tips for managing unwanted calls:

  • Don’t answer unknown numbers: If you don’t recognize the number, don’t answer. If it’s important, the caller will leave a message on voicemail.
  • Don’t provide personal data: Never communicate personal or financial information to an unknown caller.
  • Ask to be removed from the list: If you answer an unwanted call, politely ask the operator to remove your number from their list.
  • Record calls: If you receive harassing or threatening calls, record the conversation as evidence.

Consumer Rights and Privacy Regulations

As consumers, we have the right to protect our privacy and object to unwanted calls from call centers. Italian law protects these rights through various regulations, including the General Data Protection Regulation (GDPR) and the Consumer Code.

The GDPR and Personal Data Protection

The GDPR is a European regulation that establishes strict rules on the collection, use, and storage of personal data. Under the GDPR, companies must obtain our explicit consent before using our data for direct marketing purposes, such as telemarketing.

Furthermore, the GDPR grants us the right of access to our data, the right to rectification, the right to erasure (right to be forgotten), and the right to restriction of processing. In other words, we can ask companies to show us what data they have about us, correct any errors, delete our data, and limit the use of our data for specific purposes.

The Consumer Code and Telemarketing

The Consumer Code governs telemarketing activities and establishes precise rules to protect consumers. For example, companies must:

  • Identify themselves clearly: At the beginning of the call, the operator must state the name of the company on whose behalf they are calling and the commercial purpose of the call.
  • Respect calling hours: Sales calls are allowed only at certain times, generally from 9:00 AM to 12:00 PM and from 3:30 PM to 8:00 PM, Monday to Friday.
  • Respect RPO registration: Companies cannot call numbers registered in the Public Register of Oppositions, subject to certain exceptions.
  • Allow the exercise of the right of withdrawal: If you have entered into a distance contract following a sales call, you have the right to withdraw within 14 days without penalty and without having to provide any reason.

Penalties for Companies that Do Not Respect the Public Register of Oppositions

The Public Register of Oppositions (RPO) is not only a protection tool for consumers but also an obligation for companies engaged in telemarketing activities. Companies that do not respect RPO registrations and continue to call registered phone numbers may incur severe penalties.

Administrative Pecuniary Sanctions

Penalties for violating the right to object are established by the Personal Data Protection Code (Privacy Code) and the General Data Protection Regulation (GDPR). Companies that do not respect the RPO can be subject to administrative pecuniary sanctions of up to 20 million euros or, for enterprises, up to 4% of the total worldwide annual turnover of the preceding financial year, whichever is higher.

Measures by the Privacy Guarantor

The Data Protection Authority (Privacy Guarantor) has the power to initiate sanction proceedings against companies that violate privacy and telemarketing rules. In addition to pecuniary sanctions, the Guarantor can also order corrective measures such as ordering the cessation of unwanted calls or the deletion of illegally processed personal data.

Compensation for Damages

In some cases, consumers who have suffered damages due to unwanted calls from companies that have not respected the RPO can also seek compensation for damages in civil court. Compensation can cover both material damages (for example, the cost of calls received) and moral damages (such as stress and discomfort caused by the calls).

Examples of Recent Sanctions

The Privacy Guarantor has recently sanctioned several companies for violating telemarketing and RPO rules. For example, in 2023, Enel Energia was fined over 26 million euros for making unwanted commercial calls to users registered in the Register of Oppositions.

These examples demonstrate that the Privacy Guarantor is active in protecting consumer rights and that companies that do not respect the rules can face significant consequences.

Practical Tips for Managing Call Center Calls

Even if you have taken all precautions, you might still receive some unwanted calls. Here are some practical tips on how to handle these situations as effectively as possible:

  1. Stay calm and be polite: Even if you are annoyed, try to maintain a calm and courteous tone. Remember that the call center operator is just doing their job.
  2. Ask to be removed from the list: As soon as you realize it is a sales call, kindly ask the operator to remove your number from their list. You can say something like: “I am not interested, please remove my number from your list”.
  3. Don’t provide personal information: Never give personal or financial information to an unknown caller, even if they seem reliable.
  4. Don’t confirm your data: If the operator already knows some of your data (name, address, etc.), do not confirm it. You might unintentionally give them information they didn’t have.
  5. Don’t answer questions: Avoid answering questions that could be used to profile you as a consumer.
  6. Don’t follow the caller’s instructions: Do not press keys on the phone keypad or follow other instructions given to you, unless you are absolutely certain of who you are talking to.
  7. End the call: If the operator is insistent or rude, do not hesitate to end the call.
  8. Report the call: If you receive repeated unwanted calls from the same company, report it to the Privacy Guarantor.
  9. Use a call recording app: Recording calls can be useful as evidence in case of misconduct by the operator or the company.
  10. Don’t be intimidated: Some operators may use aggressive or deceptive tactics. Remember that you have the right to refuse any offer and to end the call at any time.

How to Recognize and Report Phone Scams

Scammers are always looking for new ways to deceive people and steal personal information or money. Phone scams have become increasingly sophisticated and difficult to recognize. However, by being aware of the main types of scams and warning signs, you can protect yourself and avoid falling into the trap.

Phishing, Vishing and Smishing: The Three Main Threats

There are three main types of phone scams:

  1. Phishing: Scammers send emails or SMS pretending to be a bank, a company, or a government agency to induce you to reveal personal information such as passwords, credit card numbers, or tax codes.
  2. Vishing: Scammers call you pretending to be representatives of trusted institutions (banks, insurance companies, law enforcement) to obtain personal information or convince you to take actions that will harm you financially.
  3. Smishing: Scammers send SMS containing fraudulent links or requests for personal information. Often these messages appear to come from trusted senders, such as your bank or a delivery service.

Warning Signs

Here are some warning signs that can help you recognize a phone scam:

  • Requests for personal or financial information: No reputable institution will ever ask you to provide sensitive information over the phone.
  • Sense of urgency: Scammers often try to create a sense of urgency to push you to act without thinking.
  • Grammatical or spelling errors: Official communications are usually well-written and free of errors.
  • Unknown or suspicious phone numbers: If you receive a call from a number you don’t recognize, be cautious.
  • Offers too good to be true: Be wary of incredible offers or promises of easy money.

What to Do in Case of a Phone Scam

If you think you have been a victim of a phone scam:

  1. Don’t provide personal information: Never give sensitive information over the phone, even if the caller seems reliable.
  2. End the communication: If you have doubts about the legitimacy of the call, end the communication.
  3. Report the scam: Report the scam to the Privacy Guarantor and law enforcement.
  4. Contact your bank: If you have provided financial information, contact your bank immediately to block cards and protect your accounts.

Remember, prevention is the best defense against phone scams. Always be cautious and wary of suspicious calls or messages, and don’t hesitate to ask for help if you have doubts.
