Always ask the buyer to open a suitable eBay case and only issue a refund through the case ... ensure that you have sufficient funds in your PayPal account to fully cover the total refund amount ... won't affect your account if you follow the case instructions carefully ...

A PayPal refund (separate companies) outside an eBay case can result in a loss of your selling fees and a possible further eBay refund request is not unknown.   PayPal processing fees are not refunded.

i understand that but I accepted the refund and the customer returned the parcel and i now have the parcel but the funds are still pending in paypal?

i dont want to refund the buyer and then the funds that are pending in Paypal don't become available?
