terrible service

MTN has started to have awful service. After 15 years with them I am cancelling my contract. They are overbilling, trying to collect debit orders which are not authorized by me. They send me statements on my cellphone which only give totals, when I request an itemized bill they want to charge me extra. Worst of all, I cannot contact the call centre either from my cell or from my landline. You go into a shop they refer you to the call centre. This is crazy. I don't know what is going on but I suspect the company is in financial trouble. Be warned. Me, I am finding another service provider.
