Autopay and new credit card number
I received a new card from my bank, it also had a new number (thanks to the whole target data breach). I got a notification text from AT&T today "AT&T FREE MSG: AutoPay Enrollment Change Confirmation - conf #APA**********. Your change request has been processed." Not sure what it was, but it made me think that I had to updates Autopay to the new card number. Logged in the app and it's already been updated to the new number. How did AT&T get my new card number??
