Billed on wrong account for 5 months now

I hate MTN so much for having weak access controls.<br> <br> My old account has been opened by MTN and its deducting lot of money in my account.<br> <br> From August to October its been debiting R800, recently November 2015 its debiting R2700 an account which has not been opened by me,<br> <br> I have reported the matter almost everyday, i have done affidavits every month but no help at all i have received.<br> <br> Please help me this has thrown me out of budget resulted in me taking unsecured loans with high interest to pay my creditors.<br> <br> I hate MTN so much right now i would never recommend the company at all.
