What a load of tripe in this thread.

Apparently it's alright to open mail blatantly not for you and claim it if its Christmas.

Explain to the guy that they're rare collectibles from almost thirty years ago and ask for their return. If they've been broken or have had parts lost (which is more than likely seeing as young kids are involved) then ask to be recompensed. If the figure has been reduced basically to junker status (which again is more than likely seeing as young kids are involved) then ask for all your money back (print out the paypal receipt) or if just accessories have been lost then use ebay to get a price range for them.
