Malcolm, for someone who doesn't care about negatives, you sure got upset and went to a lot of trouble to get this one removed! LOL!
By the way, you called for eBay to show up in this thread and give an explanation... I don't think they have time to send someone out to discuss every negative received, unfortunately. I mean, I have 19 (from 12 members) and I'm still at 98.8% positive.
As for how I would have gone about this one, I would have pulled the contact info and tried calling. If anything wasn't right, I'd have them NARUd for Invalid Contact Info (blocking your emails is not considered ICI... wrong address or phone number is). If that didn't work, I'd NBP them after 7 days and leave negative, and then FVF reversal. If that NARUs them, which it can especiallty if they have any other negatives or warnings, you're set. File to have the feedback removed on the grounds of user being NARU within 90 days of end of auction.
I'm sure you already have, but I'd recommend blocking her, in case she decides to go on a rampage and buy up all your BINs in a "blaze of glory". 😛
