Bad service

MTN has failed numerous times to respond on my quires. I took MTN contract more than 28 months ago, and when the Contract reached its expire date which was 24 months I informed them that I dont wish to continue with the contract anymore. I was then asked to call their service centre to cancell, whenever I am calling to cancel I dont get assistance it either they inform me they will escalate my call to the supervisor. Before that I was asked to make a payment to settle of which I did, and I should make an additional call to cancell. I would wait for 2 hours waiting to get through if my phone is not cut off. <br> <br> I have sent numerous emails requesting assistance no one is being helpful yet every they Bill me if not they suspend my number. This is very annoying and irritating. I wanted to close this contract long time ago but I cant because I need to speak to their customer care line which is not helpful. <br> <br> I want my contract to be canceled but they don't want to. Their services really sucks and is very bad
