Why would you open a dispute for billing and not non receipt of item?
Probably too late now as you are only allowed x1 dispute per transactions.
However you should have opened a dispute for non receipt of item and IF you lost due to fake tracking then >>>
To submit an appeal on the dispute that was closed, PayPal asks that you obtain a detailed report from the shipper/courier (on their letterhead or some other form of official stationary) that includes the address the seller gave them for the shipment. Or one that includes a statement mentioning your address and saying the item was delivered to a different address.
Check tracking in below link to see where it went.
