Vulkan Delux Casino: not paying out $545 win and not disclosing account verification timeframe

Hello. I wanted to leave a complaint about the casino Vulcan Delux Club. I registered, topped up my deposit twice for a total of 2000 and got lucky and won 50,000. I’ve been playing at various casinos for a long time, had losses and wins, and I never had problems with withdrawals.
But at this casino it started – on 28.02.24 I requested a withdrawal; according to the club rules the request processing time is 5 days. I waited, and on the fourth day I received an email about account verification, nothing serious, I wasn’t surprised. I sent photos of my documents (it didn’t work the first time, on the fifth attempt my photos finally satisfied them) the account passed verification. They said that after verification the timings start anew, so I had to wait another 5 days, the final withdrawal deadline should have been 11.03.24 at 14:03. The withdrawal was not transferred, I asked the operators what the reason for the delay was. The operator wrote that they forwarded the request to the finance department about the delay. I waited and waited, usually after requests the money arrives quickly, but this time nothing. I wrote again asking what was wrong. The operator’s answer was that my account is undergoing security checks, wait. I asked how much longer to wait. Answer: there are no exact timeframes, it’s individual for everyone. Now every day I write to online support asking about the check and how soon it will finish. But the answer is always the same, wait, there are no exact terms. But I don’t understand, I’m hardly the only one like this and surely they could at least say a minimum and maximum term. Of course I understand intellectually that no one will pay anything anymore, and most likely the withdrawal will either hang forever or they will say the check failed and block me. I’ve been playing for over 5 years in different casinos and I’ve never encountered this. Maybe you can help find out the maximum duration of such checks and whether I should expect the win at all. It’s upsetting when you lose so much money at casinos, and when you win you just waste your nerves trying to get that win.
