It would be nice to hear from Rollbit representative before you move further. Like leaving a negative tag or even creating a flag.
What exactly do you mean with that?
You should contact the casino representative on the forum to your concerns in this thread.
contact them and take them to explain your loss problem before you create a tag or flag for a casino representative account.
when all is proven a mistake by the casino, of course, the other members will support your flag. but given Rollbit's current reputation, I doubt they did anything that could hurt their business.
so we wait for them to come if you have contacted them.
