How telkom treat their clients.

How telkom treat their clients. I am a victim of ***** at telkom where someone took a contract phone (iPhone) using my name, I do have a contract with telkom a pocket router which I pay R140, 88 monthly. To my surprise I got a bill February this of R4800, I went to telkom store where the consultant told me about other contract. I had to submit copy of my ID, proof of residence and an affidavit stating that I have not taken an extra contract. Fast forward to date the matter has not been resolved and they billed me R28, 634 on top of that telkom is still deducting money from my bank account. On the 15th of April they deducted R2000, this month of May R8000. How am I supposed to survive with R8000 short? I have contacted their customer care a couple of times already all I get is "the case is still under investigation", and all the consultants I spoke to promised me that their manager will call me back to this day I have not received any response/phone calls. So you tell me, is this how telkom deals with ***** complains and why are they still deducting money from my account?
