Non-performing seller

A question about : Non-performing seller

Hi,
I won a pair of designer for a ridiculously low price.
They are Ј249 and I won them for Ј26 plus postage.
I had a feeling the seller would have been peed off with such a low-selling price.
Yo and behold, today I got a message from him saying he got the size wrong and they aren't a size 39 but in fact a size 36 so he'll refund my money.
My best friend is a size 36 so I sent back a message telling him so and asking him to still send them to me.
He then sent me a long-winded message saying they should never have been put up for sale (they where there for 10 days) and his wife has offered them to her cousin so he can't sell them to me.
I suspect he's pulling out of the sale because he wanted more money.
I have tried to navigate Ebay to report him as a non-performing seller but it's like the crystal maze on there.
Can anyone help me on how to do so?
Thanks.

Best answers:

• What is a pair of designer?
  Whatever it may be if you want to inflict damage, pay and await your refund or claim INR when they don't send. Either way seller gets a defect.

• Nothing that eBay will do, will make the seller sell
  All you can is to leave Negative Feedback, as its not your fault he did not use the reserve price feature or list as a BIN
