Any attorney's on the board?

Without putting the details on the net, I made a purchase for my project last year (from a non-vendor, non-forum member) and was shorted a critical item. Said critical item just showed it's face on ebay from the same seller, with a different set of claims for the origin of the item. Curious if I have any recourse to get this item? Feel free to PM me. I'd rather not air laundry on a forum so let me know what you think by PM, or I can give you more details. Thanks.
