This is not First Financial.  It is some scammer pretending to be First Financial in order to obtain your personal information and steal your identity.  And if not successful at that, at least to get you to make some bogus payment over the phone.

The calls are coming from First Financial Bank.  They called to let me know that someone's account in my household was deliquent.  BY TWO DAYS!  None of my business, SO STOP CALLING ME. Make sure you go to there website and remove your name and number if you are an emergency contact with them.
