Myntra.com — not able to add bank account details while returning items

I have purchased 3 items and want to return all the items for various reasons. There are two options for refund method while opting for return. I want to choose refund via bank account not myntra credit. But while giving bank details as refund option, the confirmation button is not enabled eventhough i have given all the mandatory informations on bank details. It seems like application only supports myntra credit option as refund method, and refund through bank is not supported. Very bad experience. Kindly look into this.
