I apply the same policy myself after a similar incident. I ordered a bunch of hard drives, when delivering them to my porter, the (dedicated) amazon delivery guy got an error on his tracking machine and took the parcel back. But then it was marked as delivered, and amazon refused to bulge, despite me receiving multiple emails the days after that delivery attempt, notifying me that the parcel would be delivered the next day (which I interpret as someone scanning the parcel they claimed has been delivered at their warehouse). A few weeks later they finally agreed to reimburse me.

Between this experience and my lack of trust in their supply chain, I now never buy anything expensive on amazon.
