***** business practice

MTN called me to advise that my contract was expiring and was no longer available for renewal. I opted for a cheaper (no phone upgrade) contract and found that I'm still being charged for my old contract at approximately four times what was agreed upon. I've tried calling the call centre (no managers available and they can't assist), messaging their Facebook account (generic responses) and mailing their legal department (it will take 24-48 hrs to respond).
