*********** services-No service delivery!

Went to MTN Richards Bay branch to query my account that's suppose to be R129 a month as per agreed contract but they charge me R389 from the start. I lodge a complaint about 3 weeks ago hoping every time it will be fixed but once again today they deducted the R389. U struggle to get hold of them at 808 and wait an hour to two hours, but they don't answer. In shop they just tell you call 808.... If and when you get lucky that they answer they tell you they are working on it... SERIOUSLY HOW LONG DOES IT TAKE??? They are quick to deduct money but when it comes to owing money and fixing wrong billing they don't deliver. I'm tired of waiting and tired to tell THEIR *********** people what the problem is OVER AND OVER! I want it fixed TODAY!!!! It will be the last time I'm using MTN!!! Is there someone that can help these people to do their work.
