I bought a Amazon warehouse Titan V, got an empty box. Amazon asked me to return the empty box after I called their customer support, so I did. Then they denied the return saying I only returned the accessories… They kept claiming they would look into it and refund me each time I called, but then would reply 48 hours later saying they never received my return. I opened a chargeback case, and they actually lied to my credit card company that I had never returned anything at all and that my return was rejected. When I called amazon, they then told me they had processed my return and that I should have been refunded. I also filed a complaint with the AG my state, and they lied to them as well claiming no return was ever requested (this was perjury).

Sometime when I have more energy I’ll find a lawyer.

Not parent, but I've had issues with returns from accidental 3rd party seller orders. I can easily imagine a niche, high priced item coming from a 3rd party seller and the whole return going sideways.
