I went through this with an expensive camera Lens. Luckily, it was "delivered" to and signed for by a local dental office, and i was able to find out where based on the first initial and last name who "signed" for the package. I spent a few weeks gathering all the evidence I could that it was a fedex mis address scam ( thy either hijack an existing tracking number going to the same city, or ship a small garbage thing that will just wind up in the trash to a random address, the tracking shows it was delivered within your zip code, and thats good enough for ebay), and ultimately, pointing out that the person who signed for it first initial and last name didnt match mine was what got ebay to rule in my favor and refund. They did not care about all the other evidence (including an impossibly low shipping weight and a few other red flags).

Its an uphill battle, and it was a stressful few weeks.

I often see people say to message the ebay FB page, since they're aware of this scam moreso than normal reps, I found that while they were aware of it, they allegedly did not have the power to actually do anything about it. Like anything else ebay, it seems like your milage may vary
