Telkom account settled but not updated on credit bereau

I had an account in arrears on my Telkom mobile account, This was handed over to a company called debt-inn for collections which I paid R500 to every month. I then decided to settle. I called Telkom accounts department and a consultant by the name of Mbali sent me the bank account with my outstanding balance which I then paid up onthe 8th of January, she promised that she would ensure that the company that was debitting would stop debitting as the account is paid up. I then paid up and sent her POP' 1month later my credit profilestill shows this as unpaid and debt inn continues to debit my account. I have called debt-inn and they said telkom has not informed them that I settled and that I must provide a paid up letter.I then called telkom again asking for a paid up letter and I was told I would get it in 14 days. Up until now i have not received this letter and my credit report is not updated. I have done all i could to have this resolved but I am not winning. This kind of service is really not acceptable, Mbali from telkom is not even responding to the emails I sent to get an update since I paid. It has now been 2 months.

The account number in question is: Account Number: *** and I used the following ref numbers provided when I paid for ref *** the amount paid was R12,356.96 and for ref *** The amount paid was R3,302.56.

I would appreciate if this was resolved as calling telkom and debt-inn is not helping.
