You can't really be forced to do anything against your will, therefore if you want them to block your account and you don't want to gamble using that account and their website, then waiting until your request is granted is the best course of action. Additionally, since I believe they have policies regarding it as well, you cannot make them block you immediately. If gambling from their casino is something you do not want to do, then stop and refrain from it. Similarly, if spending money on things you dislike is something you should avoid doing.
