Disappearing data

I'm sick and tired of buying data and having it disappear even before I use it and the call centre hasn't been helpful at all. Today alone I spend a lot of money on data that I didn't even use. All apps has been disabled for celular data as this provider would suggest. The lady checked that data came in but can't even explain where it went to besides the fact that I use a smart phone that requires data to operate. I've been using smartphones for over 4 years and have never experienced such madness. I'm really porting to CellC and not even upgrading my other contract that's due for an upgrade. I can't go on like this mos. I'm on a contract which I top up after my 1.2g subscription gets finished. Vodacom must own up and have a billing system that can show consumers exactly what they used their data on. This morning I bought 250 mob which came in and went out within a few minutes without me even being on the phone and with Cellular data off. I'm so disgusted by this. I guess the fact that they introduced powerhour is affecting them and they are not making money with calls so they somehow have to get it somewhere. Please vodacom you can't rip poor people like this.
