poor service

Mtn is useless and i regret taking contract with them ,they open a Simard contract account in my name without my permission, I logged a complain with ***** few months ago and they keep on ignoring me ,teams leaders will say they will call me and never did even managers ,now i am paying for contract i did not open..i spoke to the following people from ***** team leaders .. nothando sibiya,slindile ngidi , tinyiko , simphiwe ,complain team all of them .Its been over 6 months now ,they even blocked my numbers .but i am paying for those number .I will never ever recommend anyone to use mtn after 15yrs on being with them .
