Frustrated customer

Mtn is the worst when it comes to closing off contracts .I had / have a cellphone contract that was handed over to the SSD by MTN with all the fees that I am supposed to pay of which I did with all the hassle and increased amount that kept on accumulating. I called and sent numerous emails to be provided with a paid up letter from ssd , I was then told I should contact mtn legal since mtn refused with the paid up letter for them , I sent mtn legal with response I am now told I have to pay certain fees again that doesn't even have a specific amount even if I do decide to pay for them mind you my contract with that came to an end last month. The only thing that I was suppose to do was to pay for the months that I was in arrears than close it off.See me agin taking anything with mtn, They just **** people with all these hidden clause when they suppose to finish off or even close that contract with them.I feel sorry for all those that have just joined them, they are about to embark on one emotional roller coaster with these people once they have to pay ways
