You can report them to the FTC at https://www.ftccomplaintassistant.gov/#nb nd then you can file complaints about them at www.ripoffreport.com and similar sites but it doesn't do a lot of good. As I said, they change names and addresses constantly, almost all of them are actually located outside of the US, and they are seldom caught.
I'm glad you contacted us before you sent the money. Most people, unfortunately, contact us afterward wanting to know how to get their money back and there really is no way to do that since they are overseas and the money has disappeared.
There are a number of warning signs about scams, wanting you to send money up front, wanting you to send it by Western Union, Green Dot card, or Money Pak card, is another, etc.
We hear about almost all of them at some point so if you're contacted again feel free to ask us before you do anything.
If your question has been answered completely then I'd offer my best wishes to you and ask that you please not forget to leave a Positive Rating (of course I’d suggest Excellent!) so I receive credit for my work.
Of course, please feel free to ask any follow up questions in this thread.
