Do you have the card with you?
No, I actually destroyed it a while ago because I wasn't using it.
Oh, well, we can't change your address without the expiration date and the security code on the card, but I can send you a new card.
Yeah, but then it'll go to the wrong address.
Oh, no, we can send the card to any address, and then once you get the card you can have the address on the account changed.
