I have received two calls from this number but no one says anything!

Have my answering machine turned off until after Nov. elections due to all the political crap I get-so I just let it ring away until it stopped.

I got one too asked if it was me then hung up?

Person came on the phone and started talking to me as if I was the person with whom he was looking for.  I told him that he had the wrong number.  I do know the person, but that person does not live at this address.  He said that it was a courtesy call and would call back.  I informed him that the person did not live here.  I get tired of people calling my neighbors and relatives at my home and when I tell them that they don't live here, they still call back.  It is hot and I'm not going one (1) step to get any of my neighbors.
