Because I changed from XXXX XXXX XXXX to XXXX, XXXX claim I own them a disconnect fee which I never knew anything about until I changed to XXXX. However, XXXX kept billing me after the disconnect and I paid the first bill. I feel that XXXX should have return the money for bill me after they had disconnected me. 

The people that is calling is IC System XXXX. They use to call XXXX a day, however, the called XXXX times today. 

Thanks for any help.
