I see on these forums where a lot of people are having customer service or payout issues with their sports book. I stumbled onto allpro.com several years back. They’ve consistently gotten me my payouts by check (my preference) within 2 weeks time or less for more than 2 years now and that includes this week. I think a book is only as good as its last payout. I’ve had no problems at All Pro.
A quick Google search suggests they're a sister book to Sportsbook.com, being owned by Domain Holdings Limited. OP, the only other sportsbook you've mentioned in the past 4 years is FieldGoal - another Sportsbook.com sister site I've also never heard of. You might wish to diversify where you bet, and look at some of the higher rated books.
