I'm gonna point you in some right directions if you truly believe you've been scammed and want to try get some resolution.

First off, their license in Curacao means nothing. It's one of the shadiest licenses casinos can buy to seem legit. Curacao don't give a shit about helping the players if a problem arises. So you're just wasting your time there. Trustworthy casinos do not license their casinos in Curacao. They get legit licenses from Malta or other places.

Anyways, my advice to you is try a mediation service. Posting your complaint here is a good start but no one here is going to help you much as you've found out.

So lets start. You can try using casino sites like casinomeister: https://www.casinomeister.com/forums/community/casino-complaints-non-bonus-issues/
Make an account and present the facts and evidence. Starting with a thread is a good idea as it gets Roobets name out publicly and puts pressure on them to resolve your issue. Then from there you can use their Pitch-A-Bitch service which starts the process of a mediator reaching out to the casino directly to get a response and get you paid if the facts are straight.

Then, I would also use the complaint resolution service at AskGamblers. That's also a really good site to get the casino to respond to and present their facts or evidence. A mediator will then decide your outcome. If you go to this link you will see Roobet has responded to a complaint in the past here. Be sure to be factual and give supporting evidence to back up your claim. Do not let your emotions overtake and be professional about it. https://www.askgamblers.com/online-casinos/roobet-casino-casino-review/

I have used both of these services successfully in the past to get paid when a casino was dodging me with a payout. You'd be surprised how fast they are to respond to these mediators rather than you trying to reach them yourself.

There you go my friend. You will find much more success at resolving your issue then wasting time with Curacao or posting here. If you have been completely honest and not broken any of the sites terms and conditions there is a high likelihood then you will be paid. Good Luck.
