DSL-contract Termination

Hi O2 Team.

Sorry if I don't use Deutsch. I can't speak it very well.

FYI, I had cancelled my DSL-contract via Fax [from a O2 shop in Mannheim] since I have moved out of Germany from July 30th 2017. But still I am getting the bills for last 2 months.

The amount is getting deducted automatically from bank account. 
I had sent the cancellation fax already ref number : 01805880088 with the neceassy proof documents attached.
Also I had sent the router back via Post.

Please refund the amount taken for last month.
