You can call western union and ask where the payment has been sent. just provide the mtcns and they will tell you everything.
record that phone call and put it here. If he sent the money from online then you are right. If he didn't well, in this case he might have used craigslist to sell something and make you the receiver.

It easy if you think about it.

Do you accept payza?

Do you accept neteller?

tried it, not working.

Thanks

Hello,

I'm new here and wanted to buy some BTC. I'm planing to pay for them with my Verified Payza account. Let me know.
