The odd thing is them asking for a blank check. They seem to know what they are doing in terms of manipulating the system, however, your CC company has to comply with local regulations, even if the eWallet does not have to.
There is no proof you used the money, and there is every proof to show they withdrew your ability to pass the funds on to their merchants when they pulled out of the market for poker sites.
It seems many companies see Americans as "fair game" for a screwing over when it comes to online gambling, since it is supposedly "illegal", and they don't expect their customers will admit to having attempted a gambling transaction that then went wrong.
Here in the UK, what would happen is that we would hold the CC company jointly liable, so if the merchant fails to deliver the goods, the CC company has to refund the money. You could complain to the regulator of the CC company, whoever that might be in the US, on the grounds that it was unreasonable for them to accept this "letter" as good cause to reverse the chargeback based on your extensive evidence. This is not the first time I have heard of a merchant wriggling out of a chargeback claim by making a counter-claim will little in the way of proof. It seems to me that the word of a merchant means a hell of a lot more than that of a cardholder.
