How is a refund credited?
PayPal credits the refund according to how the original payment was made.
If you used a credit card, PayPal credits your credit card. If you used a funding source other than a credit card, your PayPal balance will receive the credit. If you used both a credit card and another source, the credit card portion goes to the credit card, and the remainder goes to your PayPal balance.
After the refund to credit cards is completed, it can take up to 30 days for it to appear on your statement, depending on your card provider. You can check the status of your refund by logging in to your PayPal account and going to your Transaction History.
