Our customers are paying by Gift Card and Top up the missing amount via PP or Klarna or CC. When issuing a refund on this order the gift card gets refilled first. We would like it to be the other way around. Gift cards should be charged primarily on orders and should be refunded only if the return sum is larger than the amount paid in "cash".
How do I achieve this behaviour? We are using 8returns for refunds and Stripe/Paypal/Klarna for payments.
