I attempted the withdrawal 2 hours ago again and it was processed. Note that yesterday I had linked my complaint here at bitcointalk when I contacted their support regarding their second day of not processing my withdrawal request.
I doubt the reason your withdrawal was processed is that they got afraid of earning a bad reputation on Bitcointalk. I might have believed that if they were constantly active here and depend on this community for new players. But they don't, and they haven't posted any updates or news in 2 years.
How much money are we talking about approximately? You don't have to say the exact figures if you want to keep it private, but you can mention the total number of digits. 5 digits, 6, more? If it's a relatively big amount that doesn't happen every day, maybe the casino did need some time to collect it from other wallets depending on their setup.
You have been paid, so you should adjust the title in a way to show the community that the issue has been settled.
