I have never heard of this site myself. Maybe a newcomer. It is a pity that none of them is active on the forum, otherwise there might still be possibilities to resolve the situation satisfactorily.
Even if they aren't active on the forum, people should still look for evidences of credibility of the site that they're visiting especially those that have money involved in it to make sure that you won't get duped, also OP, you probably should provide us some proof or do a thread in the Scam Accusations and follow the format there.
