I dont know if this is what you mean, but I once recieved an empty package and it was a struggle to get a replacement. It doesnt fit any categories they recognize. It’s not ‘did not recieve’ ( there was even a delivery pic), there’s nothing to return. I had to chat (IM) with someone multiple times.

The package gets weighed before sending and after receiving. There were a lot of articles years ago speaking of people who put stones in the package and sent it back, received the money and someone else got a package with rocks

They opt not to refund after the return window closes. You will get a generic email that the item was not received in the time alloted.

Try it, then let us know the outcome.

I once Returned three lazy Susans when I was supposed to return four. They caught me and made me return the fourth one.
