I'd agree with Kurt. If this happened to me (buyer), I'd take a pic of the box such as the ones posted, but also of the open end looking into the box, and then probably with the packing and content removed and displayed.

If you can contact the delivering postal carrier and they say the box was undamaged, you would have a pretty good indictment of the buyer, or if delivered to their front door and left until collected, the neighbors or passers-by.
