PATHETIC SERVICE

I upgraded my contract in July 2015 and specifically asked to be on a Top Up tariff to keep expenses low. On the contract I signed that day it shows MTN MyChoice 100 TopUp @ R349pm. For the last 3 months R867.58 and R2002.55 has been deducted from my bank account which IS NOT the agreed amount !! I've called the call center numerous times and had to speak and explain my problem to different people every time - because they cant find the other people I dealt with... they also dont answer my emails when I mail them to remind them to get this sorted out !! Every time resulting in promises to have my account sorted out - with no result !! My migration has still not been loaded which means I'm going to be on an open tariff AGAIN for another month. I want a senior manager to call me to have my contract sorted out today AND to have the moneys that was deducted over and above the agreed R349 pm refunded back to me a.s.a.p. !!!
