Poor service

I renewed my mtn contract in June 2015 last year,not knowing it would be the biggest mistake I had ever made.The gentleman who handled my handset upgrade at the store in Liberty Midlands mall activated the package that I had chosen with MTN billing department.After a month I found out that I am being billed R100 more than the contract I had taken up.After 7 months trying to resolve this issue with the bilking department at MTN,I'm sad to report that my issue still hasn't been resolved irrespective of my tireless follow ups with the service provider (they hardly ever follow up with me).Each time I call back I find myself repeating my story because the previous person who would handle my case upon calling wouldn't follow up accordingly and at times the request to my query is not logged.<br> <br> I'm very fed up with doing MTN''s work for them,tired of chasing up with endless calls (it has been 7 months!!! ).I asked for a buyout option and they charged me based on the overcharge they are currently billing on my contract (they can't even get that right).I have sent the copy if my contract more than 6 times to countless people at MTN.I'm really appalled at their service..
