I got a call from 815-572-4067. CID said MARENGO IL. I answered after 3 rings and after about 30 seconds of silence a real male voice asked, "Mrs. ******?" Since I am not married I said Mrs. ****** did not live here. He said, "I apologize. Have a wonderful evening." He gave no indication as to who he was or what he wanted. I'm guessing a survey or a scam.
