I got the same one. Did what you did. They told me to send the email to them (I have gotten five of them). Send the email to
[email protected] they can maybe trace the email or have their computer folks turn it in to police. NEVER give personal info to anyone you are suspicious and don't know.
I got a call last week from Mastercard. They asked for the last four digits of my SS. I hung up. That night a person called back. It Mastercard and there was an issue. They cancelled my card and are issuing a new one. I was suspicious... will not give SS out, especially on the phone.
