Never leave a message? But I see its from American Express. I don't have any credit cards from them or any company and I will never ever sign for any cards. Sadly!! How the why they treat there customers on phone calls. Ruunnn! Get to the choppa!!

AMER EXPRES (note the single letter "S")   =  American Expressions, debt collector

By the way, the Caller ID says BUFORD GA

I called the number and received an automated greeting:   "Thank you for calling American Express.....".  I hung up.  I owe them money so I presume they are a collections dept.
