Call back gets 1 ring followed by 30 seconds of silence then this recording, "Thank you for calling. We're sorry that no one is here to take you call. Please leave a detailed message with your name, address and phone number and we will call you back. Thank you and have a great day." Are you kidding? How dumb are these people? Wait, I know this one! The answer is "too dumb to ever be answered or called." A company that hides it's identity, never tells you who they are, and asks you to leave this anonymous, unknown caller a DETAILED message including your address and phone number is one of two things: A telemaggot or a fake debt collector. BLOCK IT.
