Thus far we've only encountered one instance of this issue.
ZenDesk ticket: #1152753
Donor CID: 20525984
Donor Comment: "I’ve tried to donate from the Netherlands two times today but the payment was unsuccessful. Nevertheless I received your mail thanking me for the donation."
If you look in CIVI for this donor you will see two successful donations on 08/17/2022 (screenshot below). However, we are unable to locate either transaction in Adyen via the donor email, name, the invoice reference numbers, or transaction id's. Therefore we are unable to refund what appears an unintended duplicate transaction.
The first donation details: Transaction ID: ADYEN VWRXMD994P972Q42 & Invoice Reference 127398545.1
The second donation details: Transaction ID: ADYEN JWXBFNKPHD33FKG2 & Invoice Reference 127399863.1
Do we know why we're unable to locate this at the PSP? If we can locate it appears that we need to refund the donor for a possible duplicate/second donation.
