If an item from Amazon has not been delivered, but Amazon says it has been delivered, there is no option provided on the "returns" page to account for this. I had to ask google what I should do, and it brought me to a page which suggests I should wait, look around, and look for delivery stickers. Then, if 3 or more days have passed to "contact" Amazon. It does not give any information how to "contact Amazon."
Normally Amazon delivery through Amazon is quite reliable, and they take photos to prove their deliveries.
But if another carrier is used, they do not take photos, and it appears Amazon simply takes their word for a successful delivery. It's also possible that Amazon might not understand what the carrier is actually telling them. (Later evidence suggests that's exactly what happened.)
(This has happened to me before... That time, the product was eventually delivered a week late. This time I am already over a week after the original "attempted" delivery, but only 3 days after the supposed "actual" delivery, and there has been no box, notice, or anything.)
*** Update: It seems that my formerly "delivered" item is now being shown as a return. So I think what happened is that it was damaged in shipment which was detected by the carrier, and they returned it to the sender. When Amazon was previously saying it was "delivered" it was not delivered to me but back to the manufacturer. Then the manufacturer processed it as a credit, and it seems that Amazon got that message. So I'm good, except this was supposed to be a replacement, and I still need one, but so far I've only paid and been refunded so it looks like I have to start all over.
