Buyer cannot be given neg feedback....Ebay have made it impossible:)

Spotted a tidy11630MH with orange accents and hands, complete with
: bracelet.
: No reserve and hardly any views so stuck in a bid and primed the
: ezsniper.
: I then forgot all about it till I got the mail saying I'd won it
: for €960 - Cool!
: Contacted the seller and, no response...
: 24 hours later I get a mail saying its no longer for sale and he's
: sent it to Paris to be evaluated.
: Ok, emailed him back telling him I was dissappointed as I thought
: I'd won it.
: Turns out he now thinks its worth 4500-5000CHF (~3210-3570€) and
: he hopes I'm still interested!
: HaHaHaHaHaHaHaHaHa!!!!
: Surely not(?)
: Have they really gone up in value this much?
: I could go down the ebay complaints route or leave lousy feedback
: but what's the point - Ebay will fob me off and he'll probably
: invent some equally lousy feedback in return.
: I've been here before of course but it still makes me a little bit
: mad every time :-)
: Anyway, rant over!
: Cheers,
