Feels bad for your tragedy.
Would be very nice to edits your thread scam & assumtion based on setup formats:
Scam Report Format (Use it to make scam reports properly). Hopefully they saw your thread, and your issue can be solved. The format details are quite important to make sure we can see the details of the scam accusation.
I searched a little bits about "Rollhub". Turnout Rollhubs it's a casino with previous name Blackjack.fun. Someone created a thread about a scam accusation about them, and some account from Rollhubs team is responding to the thread.

Seem you already opened a thread about them, would be very nice to update the thread with the formats. Focused on one single thread, and you can also open a scam accusation about them on Casino Guru/AskGambler as well.
