"you are still not happy which leaves me to believe that there was no pleasing you unless you got a ridiculous amount back for the pram."

Um what? A Ridiculous price? Like .... what you paid when you beleived it was the ELITE model she falsley claimed it to be so she could get a higher price for it?

I wouldnt get too stressed. Paypal and Ebay will see both sets of communication and it is clear this seller is a nasty piece of work!
