OP, i'm going to add another comment here to what i said earlier. before you quit, go in and talk to someone in senior management.
ask for a meeting with someone senior, let them knows it's important. when you get the fifteen minutes you asked for, raise you concern. it undermines trust between sales and senior management, it's a big stress, etc. give them a chance to respond. there may be a perfectly sound reason for it - the money may piss you off but it may also mean the business can stay around longer for everyone.
if you don't like what you hear, pull out your short letter of resignation, sign it, and hand it over. don't make a stink, just say, "i'm sorry, i don't think i can do this. i have to resign."
but you gave them a chance, you were heard, and you made an opportunity. they'll connect the dots, but no harsh words should be spoken (no "get bent you jerk!"). don't burn any bridges, but this will be a way to be clear about what happened, and it may create an opportunity, in fact (who knows).
i hope that helps.
