MTN worst company i've ever dealt with

<p>REQ: ********** . I have written a review and got a response that i will get a call from MTN DIrect to this day i have not. I am still waiting for MTN to sort out my query. Now i am being told there is no stock, if there is no stock why is nobody calling me to find a workaround this issue. I am paying every month for a combo deal and i am only getting half of it. I want to cancel this contract but still i am told i need to deal with a supervisor who does not care to even call me in the first place. Please advise what must i do because i am really fed up, annoyed, irrirtated by MTN.</p>
