Moved but Telkom line still active previous home

Hi, I have moved into my new house on August 1, 2015 and has requested Telkom to move my line end of July 2015. They only responded end of August 2015 with your new area do not support ADSL. Needless to say I have been without internet for a month then. I received a Telkom bill for the month of August 2015 and was not very happy. I requested a cancellation due to not living there anymore but sadly it if January 28, 2016 and I am still being charged after numerous staff members promised to escalate. When will this nightmare end I have wasted so much time and so much mails from work just to cancel due to moving residence. What can be done to move this along ?
