They keep calling and they have changed the area code consistantly over time. Every so many days they started with 313 and now are up to 972. And like the rest when you answer it is complete silence.
They call all day long and almost never leave a message. When they do they just yell my name over and over on my cell phone voice mail asking if Ii'm there and to pick up. They never say who they are.
They call my at weird hours. I've been holding the phone up to a radio when they call. Usually they hang up. When the call back (and they always do) I do it again if I am around. I'm going to block the # right away.
