Which phone are you using ?
Some have inbuilt data counters that show what app is using how much data.
Apps are available to help too.
You could contact Cs to refute the usage.
Sorry to add What are the O2 responses ??

One O2 rep said when I think I'm on wifi I'm not, another told me to turn off A few things and another said he would send me an email about how to stop this happening on an iphone... Never got the mail though.
I think Facebook is using a lot of data but I'm not using it any more than usual so I don't know why this has only happened the past 2 months.
