Transactions with 3 payment methods being one of their gift card have incorrect refund amounts. In some cases we have a negative refund which causes the payment to be canceled.

Thread with the discussion

The procedure appears to be random, we realized that the negative refund amount is the total amount requested - the payment methods that were correctly refunded - the GC amount. In the case that above: Payment 1(American express): 66,99 BRL Payment 2(Diners): 67,00 BRL Payment 3(GC): 30,99 BRL

Refund requested: 104.99 BRL

Refund on giftcard: 30,99 BRL Refund on American express: 66,99 BRL Refund on Diners: -23,98 BRL

The negative value in the Diners refund is (104,99 - 30,99 - 66,99 - 30,99) = -23,98. What appears to be is that somehow the value of the GC is being discounted twice.

There is no workaround for this bug
