No Feedback, Poor Customer Service _Telkom Mobi

I reported a ***** case over a month ago at Telkom mobile. Somebody opened an account in my name. I realised when I got debited end of May. I called Telkom Mobile immediately and I was told to send through an affidavit. A case was open, but to this day the case has not been attended to. I've been debited twice now. I call everyday to follow and I never get feedback. I have requested a letter to prove that I have opened a ***** case to send to the South African ***** Prevention Services but I never received anything back. I've spoken to countless call center agents, supervisors and managers but no one is able to assist or give me feedback. I was told the case would be resolved by the 19th of June. I called on the day and nothing had been done. I called again over month later and the supervisor tells me the case has not been attended to and it may take up to two months until its even attended to by someone from the ***** department. The call center agents and supervisors are unprofessional. No one calls back to provide feedback as promised and no one seems to care about the impact this has on my credit score as I have to reverse the funds everytime I get debited.
