mtn lack of customer service

Been an MTN client for a very long time, and get very poor service. have 1 business contract and 3 personal contracts but this does not seem to matter. they have cancelled my contract without my consent, and put it on a month to month package with extremely exorbitant rates, debiting my bank account via a debit order. i have reported it as a *****, been given the run around from dept to dept, and have spent many hours on the phone to no avail. i am so frustrated at this point because there is no follow through by mtn with regard a query. no direct lines to a service consultant, so each time your call is cut you have to start your whole story all over again..... then to add to the frustration is the sub-contracted call centres, that MTN uses but these agents don't have any knowledge of the queries, as their primary function is to sell new contracts and there is a huge breakdown in communication between these sales agents and the MTN service agents who are supposed to be in the know. i asked to speak to a manager to escalate my query, and was told that MR LUVUYO manager would call me in a few mins. After an hour i called back and guess what? i had to start my whole story again with a brand new agent who puts me on hold to call her manager and then drops my call......
