Looking at the screenshot you shared, it seems like this is another "list all your accounts in our casino" scenario from Rollbit. There have been similar cases in the past where Rollbit asked the same thing from their gamblers.
Nobody has managed to resolve the issue and get their money?
If I remember correctly, some cases that were similar to yours got resolved
with the help of @holydarkness.
