I've been getting progressively discouraged by a particular auction site that I won't name But one auction, I sold something that came in two parts... and the buyer claimed that one of the two parts was missing. I remember distinctly packing both parts because I went through a lot of trouble packaging it all into a box, and constantly repacking/fiddling until it all fit right. So, in my mind, there's no way I could have omitted it. But there we were, at an impasse, the item was too cheap to deal with reshipping, and what would I do with half a returned item. So I worked out a refund that greatly benefitted the buyer and left me feeling completely taken advantage of. So, in checking that I didn't get a negative review, I found that someone had left me a negative review that was completely inaccurate. This buyer bought something, but was surprised by the shipping cost, so we mutually cancelled the sale. The review said I was a fraud, and I should be investigated by the auction site because I sent defective parts. Anyway, since I haven't checked my reviews in a while (because I've maintained a 100% rating for over 20 years), it looks like the time for feedback correction has passed, but it still persists on my page. So now, I photograph everything I pack, record serial numbers, etc but man, what a pain... and despite all the effort to be an honest seller, I now no longer have a perfect feedback rating.
