MTN bad service

I have had the worst experience with the MTN cellphone contract every since this contract was taken I have been deducted more than I was supposed to, even after I did a change of owner ship I was deducted twice for a phone that was removed from my partner’s name, I honestly cannot wait to finish this contract because I am not happy and personally I will not refer someone or even give someone a good reason why they should go with MTN. I hope they fix their incompetence and bad service
