Worse service provider

MTN does not even deserve a one star rating. This has to be the worse service provider I've ever used. Due to system error there was a error on mtn side in debiting my account. I received sms's saying I need to pay my account or my line will be suspended. I phoned the call centre and they said they have not received any payment for my contract even though I saw the money deducted from my account. The call centre agent advised no payment was made from my account. I then agreed for him to debit my account for the payment. MTN then debited my account twice! They are refusing to assist or help my case! No refund or feedback. They have suspended my line even though my account shows that I owe no money. I have sent several emails to back office: Kristin Mabula and Mallerina( from complaints Management team). *** I have now reported the issue to ICASA , it is absolutely revolting that a service provider can double debit and just sit with your money *******ly.
