I had an Amazon item that didn't show up / got lost by UPS. The process presented by Amazon for this was pretty silly / tedious:
1) Initially, the tracking page said the item is late, maybe lost, if it doesn't arrive by X date (2-3 days after it was due), check back here to initiate a replacement / refund.
2) I went back on X date to arrange a refund. You click the button, initially it takes you to an automated chat thing that asks is this the item you are asking about (yes), do you want a refund or replacement (refund)... then it hands you over to a human and you have the same conversation again.
3) Finally, the human issued the refund... but as a gift card / credit without asking me.
In any case, it was a 5-10 minute process hidden behind both automated and non-automated chats, which is stupid and unnecessary, especially considering that these are the people that invented (patented) 1-click. They knew from their own tracking that it was missing, so it could and should have just been a single button for replace vs refund.
I suspect the steps depend on the item / amount involved, some customer risk score, etc, etc, I am sure it's all very elaborate, but in my case it was tedious.
Issuing a gift card is consumer-hostile BS too, should be outlawed if you ask me. I paid for something with money, it didn't show up, so I get the money back, simple. If I wanted to buy a gift card, I would.
