Mtn jyst fo as they please put up contracts you not aware of even if you cancel and have proof they still continue

I dont know how many times i need to complain about them there isnt once that i can say they doing wgat they suppose to be i was with them for years and from beginning its a struggle luckily i only have 1 contract left so just waiting for time to pass then im going to go to othrr provider where all contracts are currently. Each month thet add a number that im not aware of. I was on customer line for so many times i went in to different stores. At last i did manage at the one store to get it cancelled just to cost me over R6000 to get it sorted but still its not rectified
