I pay 44 with Sprint after taxes for 360 anytime minutes, unlimited night/weekends, unlimited data and no roaming or long distance charges.

Cingular used to be Cellular One and they were ripoff artists back in the day too.

Usually the other companies will give you the benefit of the doubt the first time around if you have a whopper of a bill.

I would keep calling and try to get it sorted out. The best way to get them to help you out is to be cool headed, logical, and persistent. They're trained to not hook you up but if you keep the operator on the phone long enough or ask to talk to a supervisor then you increase your chances of getting helped.
