Worst service imaginable by a service provider

Biggest mistake I have ever made moving to MTN, take my advice stay away from this terrible terrible network. For over a week I have not been able to receive calls and sms's, I can make calls though. (When you call my number it says the number is not available on the MTN network) I call the call center everyday and everyday I get a different consultant who seems to be just as clueless as the previous one and whoever they escalate inquiries to seems to be just as clueless. No one I get seems to care about my predicament, nor do they know how to help. There is no recourse, you cannot ask for a supervisor or manager to assist the clueless, all you have is the clueless.
