WORST SERVICE EVER!!

Absolutely DISGUSTING service from MTN. I have been desperately trying to resolve a R6000 account overrun issue for over 2 weeks!!! I could not check my balance because of some stupid glitch on MTN's side. Nobody answered my calls so I couldn't check my balance that way either. I unknowingly went out of bundle and I'm now sitting with this impossible bill. Out of desperation I eventually took two hours out of my work day to physically drive through to MTN's head office on 14th Avenue to try and resolve the issue. The issue was apparently logged but I have yet to have any feedback whatsoever!! I have tried to get hold of MTN representatives at Clearwater Mall, 14th Avenue and MTN's accounts department via phone COUNTLESS times without any success. The ONE time some useless individual actually answered at head office I was simply cut off and left holding AGAIN. How do you run a company like this? How do you treat your customers so badly and actually get away with it? Somebody needs to get back to me as a matter of urgency. This is quite possibly the WORST customer service I have EVER experienced!!
