When you paid for the item you actually paid to eBay. Your money is still sitting with eBay. You need to login to your eBay a/c and click on PaisaPay. In PaisaPay you need to confirm Item Received. After you confirm, Seller will get his money from eBay.
It does not matter. Just leave it as it is. Even you do not confirm receiving the item, eBay will pay the Seller in a few days. The only thing is that there will be a delay in payment to the Seller from eBay.
