If you contact us

If you contact us, we will ask for your name, address and phone number. We will also ask you several questions about your situation. We will collect and store this information.

We do this for two reasons:

1. If you call or email us again, we will be able to see what was discussed the previous time. You would not need to explain your situation again.
2. Your information is critical to the execution of oversight and enforcement tasks. The Netherlands Authority for Consumers and Markets uses your questions, indications and complaints to see whether companies obey the rules. In order to determine whether a company violates the rules, an investigation must be carried out. If the Netherlands Authority for Consumers and Markets (ACM) requires additional information for such an investigation, an ACM employee may contact you. He or she will then ask whether you would like to give a statement. That is how you would cooperate with the investigation.

You are not legally required to give personal information. If you prefer not to have your personal data stored, you could, for example, only give us your zip code. In that case, the Netherlands Authority for Consumers and Markets will not be able to use your report to obtain further information for investigations.

Collecting indications for statistical purposes

Information regarding your situation is called an indication. Such indications are used without your personal data. They are used, for example, for policy reports.
