I think I was scammed

[Bethesda13]

I have been searching for my dream watch the Rolex Sub No date, saw a post by “Skydwella” and contacted him at his email. His name is reportedly Francis Osuna. We talked over everything and he even sent me some references where he had good feedback. I paid $8k by wire (sent to someone’s account named Maria Osuna located in Pomona, California) and we agreed to Fedex overnight delivery. He was not the quickest to respond but he eventually told me he sent it by some no name courier called Next Global Delivery. Going to their website looks like it is not very legit. That was over 24 hrs ago and I still have not received the watch. He is also not responding to my texts or phone call.

Any suggestions on what I should do next? I am so angry right now.
