I had one do something that presented a different angle for a complaint... Some Amazon seller included some US postage stamps as a gift, along with a glossy full-color printed offer to pay me cash or more stamps for a positive review. So I took the stamps to a post office, some kind of manager looked at them, said they'd almost guarantee that the stamps were counterfeit. So I left the stamps and the glossy offer (with the sellers's contact info) with them, to refer higher up to some kind of investigation. I'd guess probably it will only lead back to some overseas seller who is untraceable, and who just pops back up under 10 new different names. But maybe someday Amazon will be under some kind of KYC-like obligation, to only permit sellers and other supply chain that can be held accountable for illegal/counterfeit/dangerous/stolen/etc. products.
