payment complaint

Hello, 

I am very unsatisfied with the customer service of O2. I have had a contract with O2 in Germany for 2 years which was going to expire at the end of October 2020. I decided to renew the contract and was offered a better alternative. However, due to circumstances caused by the pandemic I had to leave Munich indefinitely and on quite short notice and therefore I cancelled the new contract as of 23.01.2021 (after a long exchange of emails with very poor communication from O2 I must add). I was charged the 3 months penalty cancellation fee (for November, December and January) which I understood. I was even charged the 40 EUR activation fee for the new sim card even though I have never used it. However I thought this would at least be the end of it. Much to my surprise I received an additional invoice on top of all these payments (in total of around 110 EUR for a sim card I never used once) in the amount of 12.25 EUR for the time period 05.01 - 04.02. I contacted the customer support for an explanation but I did not receive any proper clarification on this. Can someone explain to me why I was charged extra? I find this situation very disappointing and I must say if I ever move back to Germany, O2 will never be on my list of potential providers again. Your company feels like a rip off.
