Refunds
Contributions are voluntary and are generally final once successfully processed.
If you believe a payment was duplicated, made in error, or was not authorized by you, please contact us as soon as possible so the transaction can be reviewed.
Nothing on this page limits any rights you may have under applicable law or through your payment provider.
For payment disputes or unauthorized transactions, you may also use the support options provided by PayPal or your card issuer.
