Telkom cancellation not yet processed

I have canceled my ADSL and Voice line in March 2018 and I am still being billed every month and the cancellation has still not being processed. I phoned Telkom close to 20 times with all staff saying that they are unable to process my cancelation as my account is now in arrears. I now have bad credit against me due to Telkom not able to process a simple cancellation???

Telkom please get your stuff together, the whole nation is crying out!!!
