Dear O2,
I am a former DSL home internet customer. I have left Germany on the 14th of February. I canceled the contract through a mail and even made sure that it was canceled by visiting the phone booth at Marienplatz O2. I have sent back the router and received an email saying it was returned successfully.
Yesterday, I have received a bill almost double the amount of what I normally paid monthly. I was expecting a bill between 4ht-14th of February since I paid everything before that. I don't understand why my bill is this high. Secondly, since I left the country my bank is closed therefore, the bank transfer will not go through. Could you send me the right bill with a bank transfer number so I can send it?
I have never made a “Mein 02” account and threw away the contract when I moved, now I cannot find my customer number. I only know my router number now (serial number A804018951).
Can you help with this issue?
