Customers don't understand the MTN procedures. MTN employees don't understand the MTN procedures. So who does?

16 May: Upgraded at Menlyn Park Shopping Centre with Prince Sibanyoni. June invoice: I was charged double of what I was supposed to. Everything was correct, except charged twice. I battled to get this sorted (still not sorted). July invoice: Everything correct on the invoice, however I did not receive what I paid for. I am charged for a data bundle top up (which is what I want), but I didn't get my data. Every time I follow up on this problem I get a different person and every time it is like it is a brand new issue with a completely different reason for what needs to be done to sort it. It is now nearly the end of July - a month and half after upgrading. Why on earth is this so hard for you? You have made this so complicated your own employees don't even understand the procedures! And what is even worse I have to pay extra for top up data because I haven't received the data I PAY FOR! That is a fancy way of *****ing!
