Nice to see you pop in and provide an update! And, it's good news to hear that the issue has been resolved. (Although it took you almost a month, which is still quite a long time to wait for a relatively small amount to withdraw from a casino.)
Blackjack.fun needs to improve their customer service speed drastically if they wish to stay relevant in the ever evolving crypto gambling world. They should have resolved this particular issue within a week or 10 days max.
A site's reputation depends heavily on its customer service speed. The silver lining is that op got his account back as you mentioned.
