If this is DirecTV it is poor customer service. When I answer the phone as my business (because I work out of the house) , it just automatically hangs up. So I got smart and just picked up the phone and waited for the person to identify themselves or an automated message, nothing but pure silence for 3 minutes. Any normal person would say, "I'm sorry, I must have a rpong number" or "I'm looking for "this person", an an automated message would just start the message.

This is a scam, plain and simple. A company as big as DirecTV surely would identify themselves when a person picks up the phone or at least tell you why they are calling.
