After the first withdrawal request they asked for verification and I uploaded all my documents the same day. A week has passed, my account is not verified and I can no longer access it

Stay away from them.
Looks like my account is finally verified, at least I got access to it, hopefully they will also process my withdrawal soon

DMed my login to the casino representative.
I don't know why they block the account before verification, but since I got my money all good now

Just for clarity sake, is this account blocking a new incident or still the same old complain you brought here some time ago, because I can still remember when I read your complaint that your account was blocked and documents requested. And even at some point, you acknowledged that you have recovered the account so why raise a new complaint again?
You may have to give some further explanation, to clear up things for those following up with the case.
Old complaint, sorry for the misunderstanding. It's just strange that blackjack.fun blocked access to my account right after the KYC request - all I could see was the "KYC blah blah blah" notification, so I couldn't even take a screenshot of my balance. This has never happened to me at any other casino.
