If there is a dispute, I reequire that you use Paypal Protection for Buyers.

Their Purchase Protection covers all eligible PayPal transactions.
To avail of our Purchase Protection, they require that your PayPal account is kept in good standing, and that you open a dispute within 180 days of payment.

To open a dispute, go to your Resolution Center and click Report a Problem. The Resolution Center is only accessible on a web browser, not the PayPal app.

Can I get free shipping on a PayPal return?
Return Shipping on Us is available to customers who have activated the service and have a qualifying transaction on their PayPal account. This service is free and applies to physical, tangible goods where the return does not violate the seller’s condition of sale.
