He had concrete proof that the package was sent to the wrong address and had the wrong weight. The people at Amazon weren't actually listening or comprehending. Yes, it would be possible to just ship a bunch of bricks instead of the actual product, but this scam was pretty transparent.

For this very reason, I always open packages with expensive stuff in them at my local post office, under the nose of a postal clerk.

That way, if someone tries to scam me, at least I have a presumably reliable eyewitness to what was actually in the package when I received it.
