If both payments show as processed on the donor's monthly statement,
- Verify that there is not a duplicate charge in Sphere on the supporter's contact record within their Interactions > Activities by searching an individual contact record
- If there is one transaction charge within the supporter's contact record, have them contact PayPal support to dispute the extra charge and have it dropped by PayPal.
- If there are two charges for the same transaction on the supporter's contact record, you can delete the extra charge by doing a reversal.
Please note: If the charges show as confirmed after a few days, this is most likely because they hit the back button in the middle of a registration/donation or if they hit the submit button more than once.
