Mtn quick to hander over customers without solving the initial issues we have regarding them!

I regret the day I went to MTN instead of the other cellphone companies, Mtn has brought nothing but problems to my life and its staff its the worse of them all. Even the complaints department never acknowledged complains nor even responds with those automated emails. One consultant renewed my contract without my concern, I didn't even receive a new a contract document, I was billed the same way as the previous contract I had with them, I have been paying R700 every month, this money previously was for the three devices , 1gig data and R55 airtime, and as the new contract was renewed I never received any devices but was only receiving data and airtime for an amount of R700!!! I stopped paying them as I was busy calling the call center every week to readjust and fix this matter no one bothered, if one consultant escalated the request, its either it has been sent to the incorrect team or its pending or closed without being solved. I am getting frustrated as I am being handed over for something they wont even solve. I am also listed while I tried so hard to keep my name clean. I hope as I have posted my problem here it will be attended and resolved before another year ends without any success. Mtn should learn from its competitors, they are failing dismally in treating well its customers! Their complaints department should just close once cos they are useless.
