I don't think this is an option at all. Where did you even hear of something like this or was this simply an assumption? The campaign manager(Hhampuz in this case) could know some high level individuals from Roobet, but he probably would have helped if he could a long time ago.
I really doubt Roobet would be willing to go the extra mile to resolve your unfortunate situation which is why it's best to just give up on your funds.
Forum admins, moderators don't moderate scam or business issues of any company.
Hhampuz is Roobet signature campaign manager, and he can be a contact point to Roobet team, but remember that his resonsibility is not customer support. He can ping his contact point with Roobet team about this case, but it's all Hhampuz can do.
Customer support belongs to that team in Roobet company.
