Hhampuz doesn't and shouldn't get involved in solving a case like this because if he isn't working for the casino and its security/integrity department (whatever you want to call it), he can't possible know why a player's withdrawal is delayed. But, he might be able to directly contact people in more senior positions in the casino. Like those he negotiated with when it was arranged that he would manage their campaign, or those responsible for filling the campaign wallet with coins. And that's the people who might help and provide some more clarity.
Of course, the campaign manager doesn't need to be involved in this matter. perhaps a better reason to ask Hhampuz for help, in this case, is to ask the Casino about their inactive representative account on the forum. and there are a few problems that need to be resolved. maybe with that, the representative account can come back online and explain.
it was very likely that Hhampuz could contact them. but I'm not sure if the OP is willing to do it.
