Anyone know S550? Suspicious actions

[briboxer]

S550 inquired about my BNIB 116613 on Sunday. Willing to pay paypal fees and send own fedex label.
Sent paypal to my account using name "[email protected]". Shipping to Saral Kumar in NY. [email protected].
Claims to use name "samk100" on TZ.
Checked with reference of one our members who somewhat recognized him.
Later Sunday night requested a refund to paypal account, and asked for my bank wire information. Sent right away and did refund.
Claimed to have sent wire Monday at 8:05 am, his time. No wire Monday, and communication stopped.
Maybe I am over reacting, but too much information exchanged to allow it to go unmentioned.
Anyone out there that can shed some light on this?
