Cancelation Nightmare

I cancelled my Telkom line on the 31st July 2018 and gave them my 30 days notice, I received an sms the same day confirming confirmation of cancellation with a case number and that my cancellation will be done on the 31st August 2018. On the 8th August I received another sms stating that my case number has been resolved. I have moved out of the property where the line was, so I have no access to it, hence why I cancelled the line in the first place... On the 9th September I received a new bill, for the line that was supposedly cancelled, I contacted telkom and they said they would escalate the problem... did not get a response back from them. On the 9th October I received another bill for a line that I cancelled... whoopy I called them again and I got the same story they apologize and they will escalate the problem.. still nothing.. On the 9th November I received another bill for a line that I cancelled, I phoned them again and got told that she will escalate with her leader and I should get a response very quickly,,,, On the 16th November I received an email stating that they are sorry to hear me cancel and that they acknowledge my cancellation and with immediate effect I am in my 30 days notice period....I need to note that my cancellation period will end the 16th December... WHAT A JOKE... I rep**** back to the same email on the same day that this was not the case and that this is unacceptable... WHY MUST I PAY FOR A LINE THAT I DON'T HAVE ACCESS TO AND THAT I HAVE DONE EVERYTHING IN MY POWER TO GET CANCELLED.. Today I received a phone call from telkom offering me a swop from my landline to a fiber line with vumatel????????????? SERIOUSLY, I told her the same story why would I want it if I don't have access to it, she told me that she would escalate the problem... This is seriously bull, and this is effecting my name negatively with ITC because I have a unpaid bill, because they are too stupid to do there jobs properly.
