While i agree with you about the procedure to file a claim etc to see what happened to the item, i believe 1. This should be done by the seller as you had mentioned before with Amazon and 2. The client should give the seller a chance to see what can be done to remedy the situation as the delivery company has caused them to lose face.
I however strongly disagree that Amazon is no longer liable as they shipped out the item. The contract of purchase and delivery was made with Amazon and the customer, not the customer and Amazon's or any company's choice of shipper. The person spent hard eaened money and bought an item that was promised to be delivered by the seller and legally, all issues lay between the seller and the customer not the shipper the company chose.
I never disagreed with anything you said; I feel the same way.
My only point was that I think it's absurd to expect Amazon to offer an immediate refund/replacement and be "shocked" when they say they want to call the courier and confirm the situation first.
