No way to communicate with MTN??

I have exhausted all avenues with MTN and is literally at the brink of giving up. I have called, i have sent e-mails, i even went to an MTN Store to resolve queries on my account, but no joy. This is my last resort. If i do not get a call back from a senior person at MTN to assist me in resolving my issues, then i am not going to pay a cent further on my account and i will see MTN in court with the assistance of the consumer protector. MTN is quick to remind you that you have to pay your account, but not so quick to assist when you have queries on the account.. I stood in an MTN shop waiting with the poor person helping me, holding on for more than an hour to get through to MTN. This is pathetic. I cannot even call MTN because you either dont pick up the phone or when the phones get's ansered, I get cutt off after five seconds, and i am not the only customer complaining about this. The service at MTN is pathetic and i am seriously considering moving to one of the other service providers.
