In March 2023 I have made contract in Mediamarkt at Berlin Rathaus Steglitz for 2 Sim-cards.
Now I see that I have been deducted the amount two times a month. Talking to customer service it came out that in April 2023 someone have made another contract in my name and with my IBAN and I'm paying for another 2 Sim-cards that I have never used. Customer service said that they can not help me.
Please, advise, how can I break the contract and get my money back?
