Telkom cost me a good credit review

Its been close to 2 months now that I have settled my bill with Telkom and they have not sent me my paid up letter or have sent it to the relevent sources to remove my name from bad payers.

After I had spoken to the lady that was assisting me and asked how long it would take and she assured me that a month wouldn't pass till this was done.

I had to find out after being rejected for a car finance application that this was not done by Telkom.

Now I cannot access their billing department to sort this problem out. I am disappointed and dissatisfied with Telkom for this very reason
