Telkom nightmare!

I need help to sort out this Telkom nightmare. Cancelled my account in March 2018. Received email stating they received it - automated reply. No calls, no communication that there is a problem or anything of that nature. Two months later received bills and still the bills are coming. I was declined car finance due to outstanding Telkom bills which translates as bad credit record and this after I was a loyal paying client for more than 5 years with Telkom. I am unable to get any response from Telkom after emails and emails and more emails. NO Telkom shop are willing to assist and there is no direct office information that I know of where I can go to resolve this. Just the Telkom numbers where they let you hang on forever and eventually cut your call.

Please help!
