Did you do something that is against their terms of service? If so, maybe that thing is the reason why you have been banned. If you know to yourself that you have bypassed their conditions, then you shouldn't be crying here because you'll just waste your time and effort. Even if there is only a thing that you did wrong and clearly it is stated in their policies that you will suffer repercussions, then you should have prepared for the worst. The things that I am referring to are abusing bonuses, multiple accounts, usage of VPN, using scripts and the likes that basically has the common ground of cheating on the casino.
Now, if you know to yourself that you didn't do anything wrong at all and you are a good player that follows the terms of service, then that's the time that you should take an action to secure your funds. You can post on the scams and accusations board to address your concern and to spread awareness as well. Post every detail of what happened and attach your pieces of evidence on your posts such as your screenshot of a conversation with their representatives and history/record of your account activities. After doing your part, wait for their resolution. If you won't receive any in the following days, escalate your issue to have necessary measures be done by the higher-ups or authorities.
