So sportsbook.ag has a 100K and a $25K survivor pool challenge that I won both. I split the winnings for there were multiple winning entries so I netted around $13K in winnings. They credited my account this morning and after that I was able to play a little blackjack and make a football wajor but shortly after that I sent them verification documents to begin my withdrawal process. Immediately after my account has been locked!??? Still waiting to hear back from their support. I have heard horror stories about this site but is this a normal practice after someone goes from a $0 account balance to $13K and requests a withdrawal?
