Called a couple of times. Caller ID shows LIU Nan. After an abbreviated conversation, I believe that it is First National bank Card. If it is and he is an employee of FNB card, they are spoofing the caller ID. Several attempts to call the number back gets what sounds like an AT&T automated response that tells you the number you called (402) 341-0505 IS A WORKING NUMBER, PLEASE TRY YOUR CALL AGAIN LATER. As best I read the FTC rules, spoofing the name or number is a violation.
