Hello @kafka,
Thank you for visiting our community help forum!
Sorry to know that you're not able to refund the payment. Sometimes due to technical glitches, you may face issues while taking an action on your PayPal account. This can be resolved by trying some trouble shooting steps like clearing cache and cookies from your browser or trying a different browser or device. If the issue persists after this, I would suggest you to reach out to our team through the available contact options at the bottom of PayPal page or message us through Facebook/Twitter to get this checked further.
Best wishes,
Bindu
