you will have to open a dispute on the paypal site,getting money back if and should work in your favour will take upto three weeks,and will be repaid back to your card,if through ebay you can find out there details via ebay,if lucky there contact details could show you some thhing like address and telephone number i think,go on ebay onto help-type request sellers contact details,follow there links-but it will also send them notice that you have requested there details too and shows yours (what was inputted when you signed up to ebay. police doubt you get much joy but pay pal will repay you but is long winded due to there format.hope helps a tad.
