I'm just a new powerseller and was just strating to finally get my sales up and an established 100% feedback. Last week I got my first neg. for an item the guy started out saying he didn't want and wanted all his money back including shipping. When I offered to replace no questions asked, he changed his tune to "it is broken and inefficient" and wants his $ back and blackmailed me with neg. feedback. When I wouldn't refund, he left me the neg. Since then, my store is sucking wind! More visitors than I have ever had and no sales.
Does anyone have any advice on how to deal with a neg. feedback like this? This one feeback has bsically killed my store. Do I just have to wait it out? Even if I offered to give it back now, the damage is done.
