So, the only option now is that a moderator on this forum, who has contacts with higher-level individuals at roobet.com, might be willing to help me resolve this problem for a fee.
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.
