I'm only able to contact her through ebay, so that has worked out 🙂

Sounds like that buyer of the blender may have been an eBay shoplifter. They demand a refund due to something being wrong, but refuse to return the item. I bet if you look at their feedback left for others, there are probably quite a few more negatives in there from not getting their own way.

 

It's hard when you don't have a lot of feedback, because one neg can knock you for six. It will disappear next month, so you should be back to 100%. It won't physically disappear, but it won't affect your feedback score anymore.

That's a relief. Hopefully she won't be spiteful and refuse to cancel the transaction- any idea what would happen then?

If she declines, you lose your fees and she also gets to leave feedback, almost certainly negative.

No more cancelled sales for me; It's a UPI and a strike all the way. Screw 'em. 😞

Yep, unfortunately, I was a day late for the UPI 😞 That's what happens when you give too much leeway- noted!
