6,120.59 Data bill! No details appear to exist!

I received a R 6,120.59 bill just for the data portion of my contract last month. How this is possible when firstly I am on WIFI at home and at work all day. My apps are not set to refresh or update on cellular data and on top of it all I purchased an additional 2GB of data during the month. <br> <br> I find it amazing that a report cannot be provided at the click of a button detailing exactly what the data usage was. I want to know websites visited, email data, facebook etc.<br> <br> If this information cannot be provided to a customer then how EXACTLY to you process someones bill??? What you are saying is \we have no idea what you have done but please pay us X amount for data we think you may have used but we don't actually know because we are *********** (or just sharks)"...<br> <br> 14 days to run a report on your system is nothing short of a joke! <br> <br> How about a little honestly and while you at it try and resolve the issue. If you cannot provide the information you cannot charge this amount... simple. <br> <br> My phone says i used 280 megs of data and you say R 6"
