Caller ID said: "Cell phone CA 1-213-504-7154 1:00 PM Dec 17 2013" I was not home when the call came in. Called the number back later. Used my phone company's ID block feature (*67). Got recorded female voice that provided no real information but just said over and over: "If you are not interested in receiving any future calls regarding our special promotions and would like to be placed on our ‘do not call list’ please press 1 now." I did not press 1 and hung up.
