Billed for unknown items that can't be explained

MTN SA is the most useless cell phone provider I have heard of. In June 2018 I was billed R300 odd for a supposedly music app I registered for. This was disputed and I was told it could not be reversed, but they could stop it. (I am very aware of the commission MTn makes on such wasp deals - makes you wonder why they can't reverse it.

This month (Sept 2018) I received a notification that I used up all my data and should recharge ( I am on contract and have never had to recharge. I logged onto MTN Active to find that I have been billed R423.77 for PSD Calls (Packet Switched data calls) - I must add that I have never been billed for this before. Upon calling the call centre today, they advised that I used up all my data and the PSD calls was for the data I have used up. I have not switched packets and have never been billed such a thing when I previous used all my data. The lady was most unhelpful and I seem to get the feeling that she did not know much herself and just wanted to get rid of me off the call. My contract expires next May and I will definitely consider moving to a new provider. In this day and age companies should be fighting to keep their clients. Maybe MTN does not need my business. I will be sure to share my experiences with my friends and family.
