Check your email (including the spam folder) for any notices from eBay regarding the listing - if they have removed the item from the site, there will be no trace of it on eBay, unfortunately (items can be removed for any number of reasons, so for the most appropriate advice some other info that may be useful is whether the seller is still registered on eBay, has other active listings with items for sale, and whether there is a valid tracking number uploaded to the order).
