I've made a transaction between my 2 cards issued by different Financial institutions (Banks). I've confirmed the transaction amount in 3DS window. But the total amount was decreased on a fee volume. This fee was billed by a Bank whose card was used to transfer from.
Is it required by 3DS standard to inform a cardholder about the net transfer value = amount - fee? Didn't my Bank break some of regulations - it informed me only about the amount without fee?
Transfer from MasterCard to Visa. Both Debit Cards.
