Consider: if Stake does return any amount, you have just carved out a new niche for people to exploit. What a lovely precedent! Think about it, too, as it's a conflict of interest for the casino - of course they would want you to revoke the self-exclusion - easy 'free bets'.
It's an unfortunate situation but I simply do not see any reasonable way you will get your money back.
What is this for nonsense reply?
Stake violated the rules and they should block and close the account, since he requested this.
What has this to do with exploiting?
