I have a customer who received their package, but said that the box was opened and the item was missing.
Item label was purchased through Amazon Buy Shipping, shipped on-time, and delivered 1 day early.
If the item was damaged, I’d normally send a replacement and file a claim with UPS. But since I have Claims Protection, should I let Amazon handle it, and/or tell the customer to file a claim with UPS?
The UPS tracking has no mention of damage. Interestingly, their delivery photo was taken from the street, with no details are discernible.
