The buyer received it, the disc tray would even eject at all. They opened a return request, sent it back and it turns out that the employee who serviced it hasn't properly reinstalled a small clip that holds part of the disc drive in place, which led to it collapsing internally during shipping.
Other times, we've had requests which were not our fault but simply not worth fighting. Why spend time, energy and money trying to convince someone to be a bit more patient waiting for their $5 item when you can just refund and ban them from future purchases?
Multiple times, I've been accused of all kinds of nasty things even when there's no fault or issue at all (and in 0% of cases, this has helped the buyer).
I think the average punter just seriously underestimates the difficulty of thoroughly testing second-hand goods.
Of course it doesn't seem like you want to to believe me no matter what, which is fine. I'm not sure what the point of arguing to discredit my experience is. It just drains our energy to no end. I know what I see, and you know what you see, and that's basically all it is.
People buying something without realising it's faulty is an expensive problem for me, as it inevitably means a return which is both time consuming and leaves me on the hook for postage both ways (return postage usually being a more expensive method).
If they're trying to scam with it, I doubt they'd get very far as it's extremely expensive and ruins your metrics.
