So today I received a message from an eBay buyer in Sweden who lives in a rural part of the country that Post Nord SE (the subcarrier for Royal Mail UK internationally tracked parcels) claims that they have delivered the item but 'she cannot find the item in her post box'. I am guessing that she lives in a detached home (not shared) I think due to the houses around there (Google Street map doesn't show her home) so this is not a problem with a shared apartment block etc. What should I do no...

Ebay will go the tracking and not agree to a refund. You and ebay only have her word for it and that is not enough.
