Telkom Account cancellation

I received an sms notifying me that Telkom was stopping a copper wire service meaning the conventional landline system, and was going to a wireless system. Sometime later the Consultant called me about the same matter, Thuli on the 19 June 2020 at 07h50 am. She quoted me the wireless service fee, which was expensive for me. I then declined that offer and requested that the existed copper service to be cancelled. She agreed that, that service was going to be cancelled. The following month I received the invoice for the landline service. Tried to call 10213 to follow up on cancellation, get through to the consultant while calling up my details, get cut off several times and they never call back after confirming all my details.

Eventually the consultant from Telkom phoned me demanding payment. I explained that I requested the service to be cancelled and she asked me the details of my request of which I gave to her. I was told that the cancellation was done on that day, pending an investigation on the details that I gave them. I was told that I was liable for months before their call pending the investigation outcome.

The following month again I received the account invoice, tried to call with no success. Monthly invoices kept coming. On 7th December 2020, I received the following SMS from Telkom: Telkom SA: Dear customer, Your case no ***8 is resolved. Please call 081180 for Telkom Mobile related queries and 10210 for Telkom Services and Products related queries. Please do not reply to this SMS.: I thought finally the case was resolved, until recently that I got the phone call from the debt collectors demanding payment for Telkom account.

Please help.
