MTN Still haven't do not care about customers

I have been battling with MTN for over two months regarding ********** accounts. Several calls, hellopeter complaints, emails to customer care and queries over mobile app. This is the massage that i got from MTN on hellopeter on the 3rd of May 2016: 'kindly be advised that the ********** query have been resolved and we still awaiting for a credit to be passed into your contract account,the matter has been escalated to our ***** department for the credit to be processed'. On the 12th of May, my account was suspended because MTN say I owe them R3,678.24, which was a ********** account they claim to have already sorted. When you call MTN 808 customer care, the so called consultants has no idea what they are doing. Please resolve this issue as a matter of urgency. Number is ***, acc no. A***.
