I have never talked to you before
You have ZERO reason to send me a pm
At the exact minute that you said you sent it.
Come the fuck on.
have you read upper provided skype chat


?
How did the scammer contact you? Was it just a random person who added you on Skype, identified himself as 956893 (a newbie without any feedback who didn't even reply to your PM), and you were willing to take $250 via PayPal from him?
Why would you take that risk of getting your payment charged back?
