Cancelled contract, Telkom still debiting account! and sending through Bills???

On 25/05/2017 I sent through a cancellation request to Telkom regarding a fixed line contract I had taken out. For most of the months the fixed line was dead and I would receive sms's to advise that a technician would come through to fix the issue which never happened. An automated response was sent in August to state an agent will contact me in regards to the cancellation (i.e 3 Months Later) In the interim regular phone calls was made to telkom call centre regarding this cancellation, and the debiting of my account. I even asked for them to put a stop order on my account as I requested a cancellation, the agent advised that the account is cancelled and she would put through a stop order from her side, Month after month still receiving bills until I finally went to the bank to reverse these payments (and then later learnt that telkom call centre cannot put through stop orders). 3 weeks back I visited Telkom Gateway and the consultant advised that the service is not cancelled and I have an outstanding balance to settle!!!!! Furious, I forwarded the chain of emails to telkom and the only thing she had done was escalated this!!!!! (I could have called the call centre again and they would've done that!)

This is really effing frustrating as it is now messing up my credit profile! My request to cancel was in may 2017! Telkom please effing cancel this line already and reverse all bills sent to me! Also, please do regular training with your call centre staff!
