Rigged Data Usage

Vodacom is really taking advantage of its subscribers. The data usage is rigged. I bought 350mb data and couldn't connect when i later checked balance it was gone. checked data usage, i couldn't believe my eyes. They put in things that i never used. Eg. i don't do live streams and it was there and many other things. I have uncapped wifi at home and live alone. i only use my vodacom data only when wifi is down but it seems like vodacom takes all the data from my searches which i use wifi for and use the information to chow available data. i tried to speak to a sarah online who just left chat because she realized that i new what i was talking about. It is impossible to use 350mb in 2 minutes and that was a clear give away that something is not right with the data usage.
