NO SERVICE AT MTN

I am livid to say the least at MTN. I have been trying to put a notice of cancellation of the contract I can no longer afford but have been unsuccessful in getting through on the call centre from June 2015 until today. I can no longer afford nor want this contract anymore but due to internal politics and disorder at MTN the call centres are not functioning and thus we are stuck with contracts we no longer desire nor can afford. Please can my contract be cancelled by 31 July 2015 and be converted to prepaid. Your walk in centres don't deal with cancellations and your call centres are not functioning. I DO NOT WANT A MTN CONTRACT ANYMORE WHY AM I BEING FORCED TO PAY FOR SOMETHING I NO LONGER WANT THIS GOES AGAINST THE CONSUMER ACT. THIS MUST BE CANCELLED By 31 JULY 2015 . Even the [Email Removed] email address we told to mail to for cancellations is not functioning this is nonsense MTN, CANCEL MY CONTRACT IMMEDIATELY
