Data

I am not happy at all with Vodacom. I Bought 2 GB at 08:30:20 and in less than an hour i get a notification that i am left with less than 600 MB. When i call, i am told that it is the phone that i am using, but all my applications do not update without my permission. I asked them to check their side to say which app or site is eating my data, i am told that the system is offline. And that it's unfortunate the problem is not on their side.
