Telkom account issue

I cancelled the service linked to the circuit number ********** on the 11th June 2018. The service was only cancelled on the 5th September 2018, due to a system error on Telkoms side.

I eventually received an account credit, and a payment was received from Telkom. However when I call Telkom on 10210, I get a automated voice prompt to say my account is suspended due to None payment. I have also found that I have been listed by Telkom on the credit bureau, for an unpaid account. When I spoke to someone at Telkom billing they advise that my account has a balance of R0.00.

I please need a letter from Telkom confirming that my account has been settled, and Telkom needs to notify the credit bureau of the same.

I need this sorted out asap, as the is now negatively impacting my Credit history.
