Robo call then transferred me to an Indian speaker about lowering the interest rate on my credit card.  Some of the information they had sounded right so I went along.  They wanted the expiration date on a card so they could give me a lower rate.  I don't have the physical card any longer so I was asked to find a statement.  I did but it doesn't have the full card number on it.  When I said such he hung up on me.  Don't worry, I wasn't going to give that information to anyone calling me.
