Sorry to hear this happened to you. Everyone's piling on, like they've never made mistakes. With no "hard" limits, it's almost like google wants this to happen. Have you tried contacting your credit card company? They may be able to chargeback google. Maybe you can make a case about idle capacity?
I have enabled some google services to play with (maps, calendars), that required me to put my credit card down. I'm thinking I should get a prepaid credit card so if things get out of hand, they'll shut me down rather than keep charging me until my max credit limit.
