TikiTaka Casino - They are stealing my money without excuse

I am probably not the first person that complains about the particular unregulated non-licensed casino. Let me start by saying that since 14 Jan that I registered I deposited in total 1790 euros in this site and now I have 1642 euros in there, so it's not even that I won overall, so I don't really understand why they try to steal my money. They keep playing ping pong with me between their chat and their support email, telling me to withdraw via card or via bank transfer and then, they just reject my withdrawal claiming a ''system error'' or a ''problem with Revolut bank''. Obviously, this is not the case at all. No talks about KYV or verification or anything that would suggest that this is a legit site, which I would be more than happy to do in order to get my money. The comments on gaming sites from other users are disheartening, as this seems to be a common tactic. I am not sure how they even survive as a business, but it seems they just get money without ever paying players out, so they just criminally stay open. Please help me to get my money back, I am willing to do any kind of verification if thats the case.
