I will not be filing a stiff complaint, they apparently need that money more than I do. They can donate the $200 to a charity of their choice.
What I would like is for them to stop cancelling bets which they have no right to cancel
You're grasping at straws, your examples are nothing alike. -125 to -225!=a half-point difference on a game under 2 points. Had your initial post been correct and you in fact had a prop cancelled after the game, we could've at least mustered more of a general argument on your behalf, but nothing you said was factual other than betting an NHL prop.
