Who called from 8018052891

We have received this number on our caller ID over 20 times the last 3 days. I answered once and they asked for someone who does not live here. We are not ignoring all calls from that number and they say nothing on the answering machine. Either a scam or a trying to sell something.

I have had several calls from this number no  message left(perhaps3?). Who is the party why keep calling?
