I think they are selective scammers. Hence you must be careful when dealing with them.
Overall are you sure you have one account? Because as I read in the Terms of Service the only right to confiscate your money is to try to create more than one account.
If you attempt to open more than one Member Account, all accounts you try to open may be blocked or closed and any bets may be voided. Also any returns, deposits, winnings or bonuses which you have gained or accrued during such time as the Duplicate Account was active will be forfeited by you and may be reclaimed by us, and you will return to us on demand any such funds which have been withdrawn from the Duplicate Account.
You can use this account to find many victims ---->
