No Response regarding incorrect billing

Good day,<br> My account was hacked in October 2015 and 4 numbers were added to my account and were used to accumulate an amount of R31366.71 to my account.<br> This was reported to the MTN branch office in Beacon Bay, East London and to the MTN ***** Department from whom I received a call. I have also logged a complaint with your customer care department (Reference Number ***9) and supp**** all the supporting documents requested. I received an acknowledgement and was informed that my complaint has been referred to their legal department.<br> I have received threatening SMS from MTN that my service will be suspended, which has been done amongst other threats.<br> I have received no further feedback from your customer care, although I have made a number of requests.
