This seems far from standard to me. This was an issue about a small number of comps that resulted in the casino making a huge fuss. When the player closed the account they refused to do this at first, but no sooner does the issue get esclated to here, and possibly the PAB process, they refund ALL deposits, even ones they have paid out on in the past.
This is well away from standard, which would be to close the customer's account and that be the end of it. "Standard" is not volunteering the refund of thousands in deposits, it usually has to be the player asking for their return as part of the resolution of a dispute.
It was the OP that finally made this a "legal issue".
.. and the following week we get:-
Dear Brian,
Due to an administrative decision and security reasons your account has been deactivated, your deposits refunded to your credit card and your playable balance reset.
It may take up to 10 business days for the refund to appear on your account. Therefore, we kindly ask you to keep in touch with your card issuer to acknowledge the exact date when the funds will appear on your account.
Best regards,
Finance Department
Loco Panda Casino
THIS is what it took for them to close the account. Before this, they REFUSED to close the account despite the OP asking for this to be done. Instead, they tried to convince the OP to play without bonuses, something he was doing in any case.
Now, they have a US player talking about getting their attorneys and congress involved to FORCE them to close the account. This scares them into not just closing the account, but refunding the deposits that broke UIGEA provisions, a refund the OP didn't ask for nor want, and does not believe appropriate given that the money was lost fairly.
Don't they know a BLUFF even when it bites them in the ass
Do they SERIOUSLY believe a US player is going to tell his congressman that he made deposits to an "illegal" online casino, and even if so, that the Congressman will have sympathy for the player. The most likely scenario is that such an appeal would give the FBI something to investigate in the form of a processing trail, and this could shut them down for good, and have the owners indicted.
We have already had testimony from US players who have sought help over dodgy online casinos, and in one case the result was a "tough luck" and "consider yourself lucky we didn't go after YOU as well as the processor concerned". The US authorities WANT people to get screwed over and not manage to get any redress, it will put them, and others, off playing online.
They also seem to believe that refunding the deposits will get them off the hook - it won't, UIGEA has already been broken, and they are still an "illegal" online casino taking US deposits from other players. They just wasted several thousands of "hush money", assuming of course that this wasn't just more BS.
The OP now has the upper hand, as they have been asked to contact the casino when the money arrives back on the card. The OP can therefore exact revenge by doing absolutely nothing, accepting that at last their account has been closed, and let Loco Panda go "Loco with worry" when they never hear back that the money has arrived on the card.
