That's what happens to me, too. They call and ask for me by name almost every day. Sometimes my wife answers and they seem bewildered, and the girl (it's always a girl who calls) then hangs up when my wife tells them I'm unavailable. Today they called twice. The first time they had hung up by the time I answered the phone; just now they hung up when I answered and they asked for me by name.
This has been going on for quite some time. Why would anyone want to do this?
I also get calls from this number on my cell phone. I don't answer, as I don't answer calls I do not recognize. I wish they would quit. Just so happens, I have a "Reject" button on my cell phone.
