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.
Good conclusion and its for the best to not submit KYC there since you know that playing there via VPN is illegal. There's a small chance that they will release your funds by simply sending KYC, Most probably they will just use you KYC to have a proper legal documentation to address your issue. If you are satisfied that you will not gonna retrieve it anymore, Please click the lock thread on the bottom of this topic to avoid spam and further discussion.
