Thanks Phil, I e-mailed them. Wasn't too keen on the answer though. Here it is incase you ever get the same situation:
Dear Sir,
Please note that under Help - Sportsbook Help our Rules section posts the following information for postponed matches.
Soccer kickoff dates and times displayed on our website are an indication only and are not guaranteed to be correct. If a game is postponed, all wagers will have action until 11:59 P.M. Pacific Standard Time of the fourth day after the date/time we had posted. For example, we have a match posted to start at 6:00 A.M. on May 14<sup>th</sup>, and the game is postponed. All bets would still have action as long as re-scheduled game kicked before 11:59 P.M. on May 18<sup>th</sup>. If we receive news that a postponed game has been rescheduled for some time after four days, we will immediately return all funds from pending wagers.
If a postponed game is rescheduled for a date within the four day window and then postponed again, all bets will have action for yet another four days from the last rescheduled date. This process would continue until (a) such time when the game was scheduled for some time after four days(bets voided) or (b) would continue on as long as postponed game kept getting rescheduled within four days. For example, you have a bet on a game for May 14<sup>th</sup> and it is postponed and rescheduled for May 17<sup>th</sup>, then the game is postponed on May 17<sup>th</sup>, and rescheduled for May 20<sup>th</sup>. Your wager would continue to have action in this scenario.
Kind regards,

What's bad about this is, what if the rescheduled game has different starters, goalies, etc?.. You might not want to be on the side you originally took due to any changes that may have occured. I can take the other side I guess, but then I could lose juice. Well, it's in the rules, so there is nothing I can do. I have to wait 4 days to get my money back if the game doesn't get rescheduled in that time.
Next time, I'll make sure the game is going before I bet. Good info to know.
