Zero feedback buyers keep winning my item and then not paying/deregistering

[Scorps]

What can I do? This is the second day that my listing for BNIB iPhone has ended this way

They are selling for around £400 and obviously that is enough money to want! What can i do?

You can block people with less than a certain amount of feedback from bidding. (you can choose the amount of feedback required)

Try going to the help page...

It's only offering me negative feedback, not zero option. Really

I have re-listed, and just hope tomorrow that a genuine bidder wins. We want to spend the money on the children for Xmas!

they are probably people selling the same item as yours and so are ruining your auction to give theirs a better chance iyswim.
You could always put it on as a bin and set it to instant payment only (so until someone pays it stays live)

Well i googled the last buyer, and he put UCAS number and variants of his user name had been used beofre, its plain malicious bidding

I have relisted as another 24hr auction, but will probably have to resort to BIN soon.
