All Curacao licenses are useless. Yes, on paper they are real licenses but gambling companies only take them because they are super cheap and the licensor don't ask much questions. If a player wants to submit a complaint to the Curacao licensor about a website, then the player will get no help at all. It's a complete scam.
Well, anyway, Curacao at least has a form to send a complaint about an online casino, which users can make, but here's how to make sure that the casino has a license with which there is a dispute, except for the certificate that it provides, it turns out that there is nothing else.
And I have long believed that such licenses from offshore jurisdictions, of course, are not a sufficient guarantee of the reliability and conscientious operation of the casino.
Some cunning businessmen from the gambling business organized such licensing, opened a company and figured out how they would check the reliability of the casino. And they promoted this label throughout the gambling industry in the entire gambling world. Of course, they are great that they came up with such a business.
But in reality, no one really understands how effective obtaining such a license is and what it really guarantees to players, real people, in case of disputable situations.
