Negative Star Rating for Telkom Cancellation Services!

Totally disappointed and fed up by the service from Telkom. Giving a ONE STAR RATING is being generous. Actually calling it service would be a stretch since I have had no joy from them at all. I cancelled an account Feb 2018. I received email confirmation from their agents a while later. It is now June 2019... I have been handed over to the debt collector for not paying my account (my CANCELLED account just by the way) I have emailed them almost daily and receive the same automated response. They can confirm though that my account has been cancelled. They confirm (with emails and statements) that all cancellation fees etc were paid up. BUT this is where it ends. Spoken to Thokozani who has sent several emails saying "apologize for inconvenience. someone will contact you" Spoke to Thobo last year... same reponse. PLEASE PLEASE telkom can you get your act together. I need answers URGENTLY! Can anyone help me please.
