The OP probably doesn't quite appreciate how fortunate they are that rizk and the captain will go that extra mile to get this sorted for him and they will probably get their money.
Try this stunt at one of the hundreds of less reputable establishments and my guess is you can say goodbye to your winnings. I personally think signing up with an old address is very unwise and likely to lead to situations like this. I do, however, think it would be unfair to deny winnings unless the casino were also prepared to return all deposits.
ive got say that this is spot on slotter999 it dosnt get much of a better comment on this situation as this.
