MTN most appalling Customer Services and After Sales Services

Since 2007 I had a Business contract with Mtn. However, over the past two years ever since my contract was renewed with an online MTN CCI - SA Agent, Mr Theron Pillay ***) from the Durban KZN office, my services are being disconnected at an average of three to four times a month. Currently I am being debited for two contracts instead of one. When the contract was renewed only one contact should have been in place and the other cancelled. Despite several attempts to have same rectified its seems quote" to fall onto deaf ears." Mr Theron Pillay does acknowledge the error but continuously advises me to resolve same with the Accounts Department. The Accounts Department likewise recommends that MTN CCI sort out this mess. I am now inundated with SMS's that my MTN contract is in arrears. Falling to pay will lead to legal action. MTN Account/s and CCI acknowledges that my payment is up to date yet they choose not to acknowledge same. As a result of their lack of inability and sheer negligence I now have to bear the brunt of my services being disconnected. This disconnection usually occurs on a Friday afternoon,knowing full well that there is no assistance one can receive until the following Monday. Also what's frustrating is despite directing my concerns to MTN Complaints Department nothing is forthcoming. All I receive is a reference no notifying me that my complaint will be processed within 24hrs. Both the service from MTN and their staff is appalling. MTN needs to urgently address this issue.
