It's great that everything has been resolved (or is in the process of being resolved), but what was missing was proof that the funds came from an exchange (as you yourself claim), this would have given more credibility to your complaint.

You showed your personal email in the screenshots, if it isn't for exclusive use by the casino, be very careful when sharing/showing your personal email, scammers may try to send you spam and other scams.

As Cointxz commented, you provided screenshots that didn't show the entire conversation with support, in short, everything could have been resolved more easily, you could have recorded the screen scrolling through the messages you had with support.
