......but you closed you account. what if they are sending the rest right now?
Just what I was thinking. I expect the OP was worried they would change their minds, and remembering what Betfair did to a Portuguese player (paid, then took it straight back again 2 days later from his BANK), he was probably making sure Rival couldn't try the same trick.
It might have been better to empty the account, but leave it open for a while just to see if the rest came along.
It may STILL be worth talking to the bank to ask in general terms what would happen if "companies they did business with" didn't update their records quickly enough and tried to pay or take money from the closed account.
I expect there would be a procedure whereby the OP could retrieve the rest were Rival to pay it.
This may have come as a result of Rival themselves taking over this failed casino, and finally honouring the promise made by the CEO that players of bust white labels would not lose their money.
If Rival are to survive having lost their US players, and throwing out Canadians earlier, they will have to appeal to the rest of the world, where Rival is not held in high esteem, and where competition for players is open and fierce.
