Incorrect listing on credit bureau

Telkom has a **** call centre, I've recently found out that Telkom has listed me on credit bureau for an account that I did not open, I called in and the first agent I spoke to by the name of Nthabiseng Bob, asked me to send her supporting documents, like the ID, affidavit and proof of residence, when I asked her, shouldn't I be getting a reference number or case number, she said no, the ***** department will be in touch with me, she even updated my number. I've been trying to do a follow up and everytime I get through, all the following agents drops the call in my ear, Nolwazi and Christina. In a space of 5 mins today I have called and when I explain my situation, they ask me to hold, after that, the call ends. I'm taking this further if Telkom don't get in touch with me within 48 hrs, I can't be running after them for the **** that they caused. I'm looking forward hearing from a superior.
