He is a scammer, my package arrived and it was some rinky dink $5 laser pointer. Do not do any business with him. Just glad he didn't get much out of me, hopefully he didn't get anything from anyone else.
OUCH. I kinda expected this to be the case, after see so many red flags. You should have requested for him to ship first, or go through escrow. Scammers will never do escrow.
Hope you saved the packaging. There should be an address from the sender (which is probably him), and if really another company that sent it, at least you can try to call the company to request more info on who requested the package to be sent.
