Did you pay with a credit card? Call your CC company and tell them it was Fruad.
You get your money back and your CC goes after the money.
Either way, if I pay G&S or F&F, I use a CC. I prefer the protection of my CC company, over PayPal!
I've had it happen through ebay and PayPal G&S..
I told PayPal, opened a claim and called my CC company.
I had my money instantly. The CC company dealt with the rest.
Now if you just use your bank account. Call them. Should work the same way.
IMO, it's why I pay them. Like paying insurance or a lawyer.
Edit. I had my dealings with this seller. Fpr a Spyderco Autonomy 2.. "like new, never used"..
It's in the Jswish thread.
Tho I got the knife, it was Well used. His pics are lies, just as much as he is a theif
