***** in Telkom

I have a contract with Telkom, they debited my account and said I still owed R600, I then requested the banking details and ref number wich they send to me, I then made the EFT, called in again to confirm the account number and it was confirmed, I then called in the next day and was told by another advisor they don't know that account number and I should send prove to *** I did so, I **** numerous calls because I am left without a service because the outstanding is not reflecting because they themselves don't know that account number, prove was send and I'm in the damn dark with no service, Very poor customer service. I will b stopping all payments if this is not sorted and when they blacklist me then I am going to report them. I have all my proof.
