Unfortunately, after so long, you have no way to get a refund from eBay oPayPal. If you funded your PayPal payment with a credit card, you could try calling the 1-800 number on the back of the card and request a chargeback. Have all the transaction details ready when you make the call.
if you didn't use a credit card, you won't be able to get any kind of a refund, unfortunately.
