I got a phone call from an automated system claiming to be Citibank and to call them back. I decided to google the phone number and one single link came up. Remember the rules:
1. Don't give any personal info to anyone who calls YOU
2. Don't call any number that is not PRINTED ON YOUR CREDIT/DEBIT CARD (especially one that has been left for you by and automated message).
3. Don't click links in emails. Just type in the site in questions and login.
