Sickened by MTN after sales service

My name is Ewan Lourens. I am very dissapointed with the service I get from MTN. My number was discontinued after everything have been paid up to date and I even overpaid. I went to 3 different store managers for assistance and not even one could help me after I have been struggling from the 16th of November to get my number activated again. I am loosing business. I need this to be sorted out ASAP. All of the managers keep telling me they are waiting for head office to respond to their quiries. When I signed the contract the service is great because there is commision but the after sales service is pathetic. One consultant even told me while we are busy that he is actually finished with his shift so we must wait. MTN keep deducting money for service fees and monthly subscription fees knowing the phone has been discontinued. This is *****. I want my number to be switched on and I want my money back. I even did a swimswap thinking the sim might be faulty but nothing. I will not recommend MTN to anyone. Everyhing mentioned I can back up with emails and I have all the managers and consultants names.
