Is there any way to find out how much voice and data I used for the past six months, including free socialiser data? The website seems to only tell you what you used this month. I could dig up the bills at home, that should have the information, but I can't find a way to access my historical bills online either.

 

I tried Spark online chat, but the time until I was going to talk to anyone kept going up, and there's no email option - there's chat, call, or facebook.
