When you enter their really cheap looking site, with no licence or anything, does it look like they have 26,000€ to pay you?
OP, why would you put thousands of euros in to casino like this... Its your fault.
This has happend million of times during the years, some new unfunded cheap casino is trying their luck catching a big whale.
I never ran a huge balance all at once, this was the product of some rare wins. But yes, it's becoming pretty obvious that they just can't pay this kind of win. They actually have table limits and limits on pragmatic slots, so I guess they just shouldn't be running NoLimit and Hacksaw games in general
