I had left Germany last December and requested to stop my contract on October. You are still charging the bill even though my mobile number is not available any more. Please make it double and let me know what happened. FYI, I had two numbers one for me and the other one for my wife (01*********05). Thanks in advance.
Best,
Yongkyu Kim
