re: These fraud attempts are getting hillarious

They've added to the "lower your interest rate" card, "If you do not respond, your card will be cancelled." - I started taking those with the, "I don't want the card to be cancelled. Which card are you calling about?" They say they cover all cards (in a Subcontinent accent, BTW), but I ask them which one would be cancelled. They ask, "Which ones do you have?" I tell them they called me and threatened to cancel if I didn't respond to the notice. They hang up at that point.
