Wrongfully Debited by Telkom mobile

I have never taken up any contract with TELKOM mobile and yet they constatly debiting my account I called them in two different occations and the consultants Ive spoken to are not confirming the same thing one says the is an acoount and the other says theres no account under my name with them, I even sent them a copy of the affidavit I did with the SAPS. I sent to emails to their complaints department and I havent received any feed back from them. They are messing up my name in the Bereau.
