Telkom billing after cancelling the contract

I requested for the cancellation of my internet broadband connection in the month of Feb 2018, understanding the process of 30 days notice period the cancellation should have been done and I was not supposed to be billed after 30 days. In the month of March I got the bill and then I was been informed that sorry the request hasn't been captured on our system for any cancellation. Until 24th dec 2018 I was regularly following up regarding my cancellation and then one day when I walked to my bank to apply for premium account my case was dropped as I was told that your Telkom account is running in arrears. I was really upset as I had never been defaulter in my life and always have made all the payments in time.

When I called Telkom, I was assured by the Telkom senior officials that I will receive a call, I was also given an email so that I can raise my concern to the Telkom credit management department and since then no response.

The email provided by the Telkom official was ********** The email was sent on 24th December 2018.

My credit score and rating has been spoilt by telkom due to negligence.

The case no. For the above concern is ********** 5
