Mtn Sucks!!!

Made a payment arrangement with Mtn. Sticked to it and even paid a bit more in order to keep my line open. Still it gets suspended. I made payments towards my outstanding balance for the past 4 weeks only to be told my the supposedly service champion that I last made payment in September. Sent in proof of payment, but my line is still suspended. Mtn sucks big time! That is why I cancel my contracts one by one.
