I sold a compilation CD and the buyer left me neutral feedback as they didn't like the music! I asked ebay to remove the feedback as it is unfair but they refused. How can it be that I get neutral feedback for something that is not in my control?
I had some of my listings as GTC as I assumed that when they were auto-relisted they would just use the 100 free listings a day. I now see that in fact I've been charged insertion fees for these. Why is that?
