It's been a while i played on blackjack.fun last, from the screenshot you shared, I see you have previously withdrawn 0.3 eth which went through successfully, how long did it take before that withdrawal was processed?

And again, for an active casino, one week is already more than long enough to wait for a withdrawal to be processed, have you tried contacting their customer care service, what did they say?, if you haven't, I will suggest you contact their customer service from the site, since you are likely to get a faster response from their team there, i don't know when last op was online here though.

And keep us updated.
