What's the protocal for a mis-posted bet?

What's the protocal for a mis-posted bet? I just hit the Chargers +7 "Live In Game" on Bookmaker. Can they just repeal this whenever they want, even though all on-line wagers are final? Should I contact someone now to ensure that the bet is honored?
if it's a typo there's no way cris pays. you should call them n let them know
Your best move here is to call them, apologize, and be less of a douche in the future.
