I bought a wooden musical instrument on Amazon marketplace years ago. It arrived and it was a POS... Shit quality, nothing like the photos. No problem, I'll return it to amazon. Found out I'd bought it from amazon marketplace actually and amazon wouldn't help.
The company who sold it could barely communicate in English and just said 'well what do you expect, it was cheap'. Amazon again wouldn't help, just said pay to send it back and the company has to refund you plus postage. The company was refusing, with garbled English.
All this took so long eventually I just gave up. Then a while later I realised that the instrument had little piles of dust regularly appearing on and around it.
It had fucking woodworm. So I dumped it but much later realised the woodworm had spread to my nice wooden speakers, which then also had to be dumped. No recourse from the company which sent me the pestilent and misdescribed musical instrument, of course!
Amazon is bad now compared with how it used to be (if anything goes wrong get ready to lose hours of your life on chat or phone trying to get it sorted and multiple agents lying and/or hanging up) but their marketplace is the worst.
