***** on my Telkom contract :Ref***0

I was doing a check on my ITC late last year in December and picked up a discrepancy on my Telkom account. I am on a R199.00 contract for my Blackberry Q10. On my ITC I picked up that my account with Telkom has changed from R199 to around R4900 odd. I disputed this with transunion and they advised they will look into it. I then called Telkom in early December regarding my account only to be told that my contract was upgraded. I advised them that I have not been into a Telkom or changed my contract in anyway so it was done **********ly. They gave me a reference and advised that I would need to submit and affidavit and ID which I have.I submitted this all around mid December and was advised it would take 5 working days. Today is the 15th and after calling in for the 6th time wanting feedback I am told they cannot call the person who is investigating this ***** (Lambert) and there is a note that he tried to call me on the 4th January. There was no voice-mail and on both my numbers that I supp**** to them. Today they debited my account with an amount of R1500.00 and I am told that I just need to wait for feedback and the consultants have emailed him (Lambert) but he does not respond.
