Actually, I totally forgot that this casino doesn't actually have a license but is
pretending that they do, lol.

This is a straight-up lie. Their license doesn't exist. Therefore they aren't actually being held to any kind of regulatory standards, and its gonna be really hard to get this money back even if OP does have an actual case (which we don't know - none of us know - we are just taking OP's evidence in good faith).
Still, this is bad and I think Xyes should be tagged for lying about their license. There is a
flag but I am the only DT supporting it, and surprise surprise, guess who is the only DT opposing it...
Since Xyes does not provide any kind of license number (they
formally provided a made-up one, LOL), its impossible to verify the existence of their license. Several casino review sites have also stated that Xyes doesn't have a license:

We’ve talked about more important things than the games and even the bonuses, both of which are a point of reference for a quality online gambling site for many gamblers, some of which may disregard the most important aspect of any iGaming site, which is the license.
Before we move on to the many qualities that this online casino possesses, we need to inform you that it operates without an official license.
For those who are new to this online gambling world, it means that there will be no official third party to uphold the laws and regulate the casino and if some kind of dispute happens it will be between you and the casino itself.
Damn thats a great catch, that alone is worthy of a flag. I will support it as well
