call from this number, no voicemail left

Got a call from this number and had to say hello about three times before someone answered.  Then they were asking for someone who doesn't live here.  Then they insisted they had the right number after I told them repeatedly I was the home owner and that no one by that name lived here.  They still wanted to know if I was sure they had the wrong number. I gave up and hung up on them.

Received call from this number and when I picked up no one answered after I repeated, " Hello....Hello"!
