I got a call for this number and an automated message said, "This is Chase Bank, calling you in investigation of a security issue with your Chase Bank account. Please enter your 16-digit card number to verify ownership of this account." I punched in my pin-number and then hung up immediately, realizing that it was probably a huge mistake. I called my bank and they confirmed that they had never released a call like that, nor would they, and I had to cancel my debit card and order a new one.
