s been there. it ended up we were using too many texts and getting online too much along with my little bro ( he's on our fam. plan) deciding to talk to his new g friend every second of every day. Yikes.
THe company worked with us and set up a payment plan, we have cingular/att btw. I know most companies i've had you can push certain number combinations on your phone and it will tell you how many minutes you've used.
If you can't figure out what went wrong just by looking at your bill, call the company, they should be able to tell you exactly where you went over. My dh used to work for a cell company, its easy for them to look it up.
Hope you can get every thing worked out.
