I’m reminded of a tale from my early days of working in tech support back in the mid-90s.
Customer rang complaining about their new computer, saying it didn’t have a video card. I spent, oh, a good 20 minutes with him ascertaining that he had a fully working PC; he had a display therefore he had a video card, there were no holes at the back indicating that something was missing, etc etc. Then he indignantly asked, “well, where do I put my tapes in, then?”
Goods have to be as described, not “fit for purpose” where purpose is some random usage they’ve made up. What are you supposed to be contacting Ebay about exactly?
