MTN Worst provider in S.A

i have made countless phone calls to MTN as they have failed to do their jobs.<br> i had asked to have my *** contract to be disconnected for 3 months after my contract had ended which has not happened.<br> they suspended my account and said that i owed mtn money which was not the case as i have all the emails since November confirming my contact would be migrated to PAG but never happened.<br> i had an agent that was rude to me as well as raise their voice at me the manager promised me a call back which never happened MTN is becoming the worst service provider in S.A and when my contract ends i will be leaving i have been with MTN for over 12 years and have been treated like dirt. is this the way long standing customers are treated. <br> <br> MTN has promised me so much but has delivered nothing.
