You need to complete unpaid item disputes against her for every item she has purchased. You must open the disputes within 32 days of the end of the sale and close them by day 36.

Set your buyer requirements as tight as possible too.

I hope you're opening non payment disputes against her for every unpaid item. these will helpmget rid of her from ebay and do us all a favour.
