We had a couple donate twice to us in February. Each donation was made in memory of someone, complete with the address to send the acknowledgement card to. We sent them a thank you email, sent the donation acknowledgement cards, and published their donation in our newsletter to thank them, and now, three months later, they are disputing the donations with an "Unauthorized Transaction" claim. In the first dispute, I just issued a refund, because I figured it'd be simpler to just do that and be done with it. But then I got an email from PayPal saying the the case was closed, the money was refunded AND there was a $20.00 chargeback fee. Now they're disputing the other donation. I sent PayPal screenshots of the donations including the memorial information given. I don't really have an issue refunding the money they've donated, but being charged $20.00 every time someone disputes a donation adds up quickly, and now we're having to use other donated funds to cover their chargebacks.
Is there anything I can do in this situation to avoid the chargeback fee?
