Go to your Paypal account. It should still be there.
However you are waaay too late to open either an Item Not Received Dispute (45 day deadline) or to leave feedback and the more important Detailed Seller Ratings (60 days).
Instead go to the credit card you really paid with (Paypal is just a useful mediator) phone their 1-800 number and ask the clerk about a chargeback.
Have all your date, currency, and transaction number information handy for her to process your refund.
But do this now, cards also have deadlines on claims.
