Getting screwed over on a payment for a parts purchase?

UPDATE UPDATE UPDATE
GOOD NEWS, for a Sunday morning, when clicking on my computer.
The John S. that doesn't use his middle initial in his e mail address, the wrong person that Pay Pal went too, send me the money back into my Pay Pal account.
So the $113.00 is there for me to spend, this time correctly to the correct person.
Believe me, i am a very happy camper this morning.
Now to go over to the super market and do my grocery shopping, and spend some $$$$$ over there.
Thank's to all for your tips, patience, understanding, with me in my problem.
It worked out well.
