with 1xbit's reputation on forums, and many similar cases in the past. I doubt he will get his money back. how often he would contact support, but he would not get the expected results.
what can the forum do in this case, the warning is already given with the tag as well as the flag. but still, they get victims. the forum does not moderate this kind of thing, all attempts have been made. it's just that those who play with money at the casino, of course, are responsible for their own money. I hope he will get a replacement from betting at a more trusted casino.
