Capital One: Don't train your customers to become ID Theft Victims

So I got a call from someone claiming to be from Capital one wanting to discuss how some changes in the law would affect my account. He proceeds to state the last 4 digits of my account number and that he'd need to confirm details of my account before proceeding. In other words, he wants me to give info that can be used to access my account to someone who called ME. If you need to send me information like that, use your web site, a letter, or an e-mail. Don't make me give out my personal information to someone who calls me, as I can't really be sure they are who they say they are.
