I received a call from this number on 3-22-07. When I started to ask questions, they hung up on me. I called right back and this number does not receive incoming calls. So, I called Cardmember Services (my visa Card)and asked them if they had any knowledge of a phone call to me. I was told that no one there had called me, he had no idea who had made the call to me. I am on the do not call list. I do not understand, because I am always getting these types of calls.
