Telkom unwilling to assist

I have had issues with Telkom since the day I signed up. I eventually closed and paid up my account on 22 December 2018.

My credit report however states that this account is open and unpaid/overdue (more than 12 months after the account had been paid up). This affects my score and therefore my ability to obtain favorable rates.

When I speak to Telkom telephonically every time, the call centre agent confirms that the account is paid up and closed. When I then request a paid up letter, I amd promised that it will be sent to me, but it is never sent. I have phoned the Telkom call centre on several occasions, but it is always fruitless.

The impression is created that Telkom is not interested in assisting me in this matter.

I do not know what to do anymore.
