Gatvol MTN customers

MTN has gone down in service Apart from a watch I took out with my contract that got stuck in a bootloop(not their fault) the process of getting something done was a NIGHTMARE. Every Friday for 3 or 4 months I would go in and ask how far and what now. They kept telling me lies and *******. SAMSUNG was amazing as I contacted them direct and in a week or 2 I had a new watch. NOW my mother's phone gets suspended each month due to account being in arears, she pays each month and the amount they say is out standing keeps increasing with each month's amount. She has sent proof of payment every time then they switch it back on just for the same process the following month. We are a family of 3 with MTN and think we will all be ending our contracts.
