After ignoring several calls a week from this number (no messages were ever left), I called it myself. Keith answered "Direct TV". I asked him to remove my number from their call list. We'll see....
So, after reading these comments, I thought I'd call DirectTV to either confirm or deny this phone number as belonging to them. I agree with a previous post that I will not state to a stranger whether I have a system or not (I am a property claims adjuster, and tend to be hyper viligent concerning security). They could not confirm this number, so y'all can chalk it up to SPAM.
