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

First, you said your account was finally verified, and you are waiting for your withdrawal to be processed,
And now again, you come back to tell us you don't know why blackjack.fun blocked your account before verification, but all good since you already got your money ....
What exactly are you saying bud? Did they process your withdrawal and blocked your account?
I thought you said above that you've been verified and waiting your payment?
