Apple does not approve or deny cards being added to Apple Wallet. The account is owned by the bank and technically the card is the bank’s property. I even dare say the arrogance is yours.
The bank that issued the card and the Payment Network Operator have final authority in regard to adding a card to an electronic wallet.
Your resolution is to persuade your bank to add the card and then persuade the bank to tell the PNO to also authorize the card. When the PNO sends the token, Apple will add the card, per their authorization to do so.
Just ask the bank why they are >Red Pathing< your bank card? If they tell you why, it possibly can be fixed.
