Have you recently purchased any items yourself from eBay? Then find those sellers, and down the left hand side of the items listed click on the filter Sold. See if any of the items you have, appear there.
If so, contact those sellers to send you enough money to cover postage to send the items back to them, do not be fobbed off with sending to the correct buyers.
If you cannot find the items, all you can do is hand the items back to your postie when you see them , and tell them the person is unknown.
I'm presumeing there is no name and address on the back from the sender?
