Minutes and data

Evening my name is Boitshepo and I am very disappointed with mtn service, I recently upgraded my contract and from my understanding I was supposed to be getting 240 minutes for all networks but somehow that's not the case. When I inquired about it I was asked for my contract that I never received since the upgrade, I am honestly fed up with mtn and I want them to tell me exactly what I signed up for. The worst part is that the data is supposed to be 2gig per month but during the month I can't log on to the internet because it says I ran out of data even though I still have 900 and something MB. Mtn must just their act together.
