MTN deducting more than its due to them

on the 15 october i Received an SMS indicating that MTN has deducted an amount of R1544.33 from my account and when i called the call centre i was tolk that another account was opened under my name somewhere in gauteng and by those days are was no where close to gauteng and thats when i submitted my information to the ***** division through a consultant Named Zanele Radebe who was very helpful and when i call the call centre in the two weeks following the incident and i was told that the investigation is still continuing and then on the 3rd week i called and was told that the investigation has been closed but what really gets me is that from that invetsigation no one called me to tell me what was the conclusion reach and also what is the way forward and to make it worse am being told i have to pay another amount of R436 which i donot understand as i have paid all my mothly subscription amount for the past months and have not skipped any.<br> even went to a branch in Brooklyn on the 23 November to ask why is that and they indicated that they donot understand what is happening in my account so can someone from MTN really explain what is happening because it is really getting frastratin
