eBay

I RECEIVED AN OFFER ON AN ITEM WHICH NIS LISTED ON EBAY. UNFORTUNATELY I DID NOT SEE THE OFFER UNTIL IT EXPIRED. I WOULD LIKE TO GET IN CONTACT WITH THE PERSON WHO MADE THE OFFER--HOW DO I DO THAT? PLEASE RESPOND

IS THEREE A LISTING OF BUYERS WHO HAVE NOT LEFT FEEDBACK ANYWHERE IN MY ACCOUNT INFORMATION??
