Poor MTN service

Hello Peter

I have been with MTN for a lig time now and recently my WiFi contract expired. We reversed our last payment to MTN because we were billed R200 more than what the contract usually is. We then phoned MTN to ask what's going on. They only then let us know that we would be billed normal rates. I feel that something like is should be disclosed with the customer before just increasing rates. We are very unhappy with MTNs customer service. We now have to pay two months of normal rates (which comes up to R1089.59) before we can cancel and close contact. Is this fair to the customer/consumer?
