Yes, you have been scammed. The site was the latest one in a long string of identical fake sites (all with different names).
The forums you saw were also all fake and operated by the same scammer. Actually they are not even forums but just single sites mimicking other legit forums.
You need to file a police report; and the police needs to be aware of this being an ongoing fraud. I'm abroad right now; once I return I can provide you with an (incomplete) list of the domains/sites used by the scammer since late 2015.
