Contact the seller. If its an Ebay purchase go through the resolution centre under 'I have not received item'. Hermes have no proof of delivery as no signature has been obtained,therefore they are liable but its up to the seller, not you, to try and get compensation. If the purchase is through Amazon or any other seller they should re emburse you or send you a replacement. I've had a couple of 'no show' parcels from Amazon and the sellers are very good about replacing or refunding. Another thought...have you checked with neighbours that someone hasn't taken it in because of inclement weather?
