Haven't logged-in since last week, will read through all the posts. Thanks for all the replies and advice.

I believe the site to be one of the largest and for sure reputable on this site. I've always wanted to place sports bets but it is illegal in my state. Almost every website recommended this site for US betters while using VPN. And in fact I logged in using different countries for almost two months, and they never gave me any issues, so I thought it was kind of a "look the other" way type of thing.

I did talk to customer service and they said there is absolutely nothing they can do until I submit KYC> They said no one has the ability to unlock my account except the security team, and they cannot talk directly with the customer. 

I kind of made peace with the winnings stuck in there, and no plan at the moment to try and retrieve it via a mule.
