How do I complain?
Contact the operator you consider responsible.
If the operator advises you to complain to a reseller but that complaint does not yield results, you can again contact the operator with whom you have the subscription. The operator is responsible for the services they bill you for, even if they are sold by resellers.
If the operator cannot resolve the issue or if you do not agree, we recommend that you also send a written complaint to the operator. This can be done, for example, via My pages, chat, email, letter, or contact form. We recommend written contact because you can then show that you have complained and when you have complained. You should save a copy of your complaint.
If you have sent the message in an appropriate manner, as in the examples above, it is considered to have reached the company regardless of whether it is distorted, delayed, or does not reach the operator. However, you must be able to prove that you sent the message and when if the operator claims it has not been received.
If you choose to make your complaint verbally, we recommend that you ask for a written confirmation of what you agree on. You can also ask the operator to make a note of the call.
