MTN Contract **** & POOR CALL CENTER AGENTS

If I could give zero rating, I would. I migrated my MTN contract to prepaid in April and stopped receiving contract benefits and invoice as my contract was completed. MTN kept on charging me for the contract and now they have handed my account to collectors for a debt I don't even know where it comes from. On top of it all, the call center agents have been horrible - they keep on moving my call from one department to another and then drop my call knowing it is difficult to get hold of me. They are so poorly trained and MTN as a whole it is a **** company. I will be taking this matter to national commission.
