Help, Telkom is ruining my like!!!

I cancelled my Telkom line, in advance, in July 17, due to relocation, per Telkom mandate. The bills kept on coming in so by October 17, visited a branch to investigate. Of course, they said 48hours later the problem will be sorted. By January 18 I had a bill of over 5k and black listed. Phone calls emails later, paid the 5k and reported the issue and re-cancelled, including chasing up to clear my name from bad credit. By March nothing has changed and more bills. I visited a branch again and repeated the whole process to cancel.<br> It is now July 18 and I have a bill of over 5k and bad credit rating because of Telkom. Incompetence and theft is at the helm of the day. What do I do? What do I do? Help!!!
