Still ... he was quite clear in his description that the auction was for two holo cards ... and the missing card was quite valuable ($20 to $40, depending on the reference site). The only saving grace is that it went for the minimum bid of 99¢, so it's not like I had fought through a bidding war to get the holo Dark Charizard only to find it wasn't available. However, there should be some response.
I have never left a negative feedback, and I'm not sure this (which appears to be a mistake) qualifies for one, but somehow leaving a "neutral" does not quite convey the "I feel like I've been had" message sufficiently. As I noted, I could report him to eBay for a "fraudulent listing", but that would be icky karma, especially given the small "investment" I have in this. I suppose I could demand some resitution, but on a 99¢ win, I'd hardly feel OK with that.
So, what to do? Just leave a "neutral" feedback with a harsh description of the issue? Press the matter with him? Narc him out to eBay? Leave a ("This goes on your permanent record!") negative feedback? How would y'all handle this?
