Received a call today, 2-5-14 @ 11:40am. I did not answer. I receive calls like this several times a day. I never answer if I don't recognize the name on the caller ID. I even disconnected my answering machine, after a while they stop calling.
I got phone calls from this number several time these days. When I picked it up, nobody talked. Calling it back, the line is either busy or no answer. It is annoying.
