From your post, it appears that the buyer has not communicated with you. I'm surprised that they didn't say anything seeing that it took 8 days without notification from HI to get to NE. Most buyers may have submitted an INR, or at least contact the buyer when they see no tracking movement for 2 days.
As for the item, does the wrapper has a "freshness" date, or "best if eaten by" date? From what I see in your posting, you indicate they are fresh from Europe, but honestly, how "fresh" are they? I understand your concerns about temperature and all that, but lest be honest, they certainly where in a cargo hold from Europe, as well as HI temperature. I don't think it is spoiled and its still eatable, but i leave that at your discretion.
If buyer comes back, you should certainly ask for shipping again, seeing it was not your fault that the item was undeliverable. You can google the address and see what it comes up, at least that will give you an idea if something is odd. Mahalo.
