If I'm understanding this right, the problem is on Bookmaker's end. Circle isn't going to delay acceptance of bitcoin transaction. They don't even have that capability. If it's sent, it shows up on the blockchain.
The only thing they can do is set a minimum amount of confirmations needed for you to control the funds.
If Circle closes your account ,they now set a time limit in which you have to withdraw funds. You can withdraw funds in your account until that date.
