I called o2 customer service in January/February by phone and tell them that I moved away and terminated my contract. I received the response from the customer service rep for both calls in both months the contract is terminated and I won’t be charged. And I am still getting money pulled out my bank account.  

When did your contract minimum term end? Or did you have a contract with no minimum term?

You can't terminate a contract in a shop, you can only have them submit a termination request for you. Did they give you a copy? Did you receive confirmation in text form that the contract had been terminated? The status should also be in every invoice.

The person at the store counter did the phone / internet cancellation for me since I am not German and leaving the following day. He submitted the form and the only thing I had to do was ship the internet router back to o2 via DHL down the street with the shipping label they provided. I never received any confirmation in text only via conversation at the store and other o2 representatives over the numerous phone calls.

Hello @GT1092 ,

welcome to the o2 Community .

We’d be happy to take a look at the contract and what’s going on with the cancellation. As your community account isn’t connected to the contract, we’ll need some infos from you first. To that end, you’ll be receiving a private message from us, you’ll find it within your inbox. Please let us know if you answered here.

Kind regards, Sven
