yeah...ebay will provide you with the address she has registered with the account if you have bought from her..."request contact details" i think the form is called...this could be a false address however. try:
http://shop.ebay.co.uk/ebayadvsearch/__W0Q...c=1#ContactInfo
p.s. just because PP have 'released the funds', doesn't mean she has withdrawn them to her bank account...if you start a dispute I believe she won't be able to withdraw the funds to her bank. if she has already withdrawn them to her bank account...you could win the dispute but still not get any money back as her paypal account will be empty...it will put her account into a negative balance.
if you need help finding her number, address etc I may be able to help you in a few days...you should have her real name from the paypal receipt. pm me if you need some help
