I don't need my account again, but I want my affiliate money!
You don't need your account again but you need your affiliate money? Now that's a funny one I've heard. Gaining control of your account is how you get your money back. No one is going to process your withdrawal for you less you get to do it yourself so, you would want your account unlocked.
They say they have the right to close any account without any reason and confiscate its funds.
This has got to be the worst T&C I've heard of and I don't think it possible as no casino or sports book would ever put that up. Perhaps not stated in clear terms but, I would like you to quote them directly on that let me take a look. that would be so unfair policy, there have got to be a reason, even a stupid one at least.
