The first mistake you made was playing and depositing at a casino, which is comparatively a new one. There are already many trusted and reputable casinos present in the market, but you went for this new casino. Now that you have made the mistake of joining a new casino, you should at least read their terms and conditions before depositing any money. These new casinos often block players’s funds by stating any rule from their terms and conditions page. Nothing much can be done. The best you can do is contact their support team frequently and open a thread here in the Scam Accusation board.
