Well sorry 2 hear that. If it was BTC sent forget it, most scammers find a way to get your money so you can't get it back. I've been scammed about 3 times recently. One for a work at home job, another for a car, and some homes for rent. Watch out for the groups on Facebook I would say 90% are scams. Once you message someone or DM them they get saved as a friend and if you send them money, forget that. Best advice, live & learn & do your research first. 
Good luck 

 Thank you sm
