MTN SOUTH AFRICA NOT TREATING CLIENTS FAIRLY

I am a customer with MTN for almost 30 years i have 6 registered devices on paying R3600 pm. Last year i upgraded my daughters phone as usually 4 months early, like usually. I was never informed that from the beginning of last year that you will pay 4 months in om the contract, which makes it a double R3600 for a once off at the end of May. Because i was unaware i started getting bills double my payment, phoned MTN customer care three times spending almost h an hour on the phone trying to find out why they say i am in arrears. I received an SMS the other day that the arrears is on my daughters early upgraded phone. Its January my contact is suspended, i made an arrangement to pay month end, my contact cannot be opened, which i paid for already before arrears are not paid. This uis not traeting clients fairly. Mr Ombudsman there is a serious tcf problem at MTN. Stay away from MTN they are dishonest an not treating clients fairly
