Telkom destroying my credit score

I have been experiencing a lot of problems with my telkom line and account.

The account was opened in 2017 for Home fibre uncapped 10MB. Internet worked perfectly until February 2018. I tried to use the contact center for help - Problem was not resolved I logged a call for a technician to come out - No one came out I then contacted the call center to cancel my line - I was told I have to log in to cancel the line (When I ordered the line I was told I can cancel with 30 days notice by calling the call center - you can check the recordings) My line was disconnected by telkom on 16 August 2018 due to me stop paying for a service that I did not get (I made no payment from March 2018 till date, also had no internet but was still billed) I eventually went to a telkom store on 25 November 2018 when I noticed my credit score being affected by telkom - they could also not help and just called the same call center again. Case number ********** 6 was logged on 25 November and still not resolved to date. I then logged in to cancel my line and was called by telkom customer retention who helped me get my line fixed and promised to escalate the billing issue. The next bill I received was even more charges and no credit for the 9 months of no service.

Today I logged in again to cancel my line but the online portal does not allow me to cancel my line!!

I am stuck with a bill that keeps increasing, affecting my credit record and you are not allowing me to cancel my services!!

I urgently need someone to contact me that can assist.
