Shows as "Kirkland WA" in ID. Rang four times and stopped. Called the number back and got recording: "This number is not accepting messages at this time." Am blocking number.

My Caller ID said "unknown caller" but I picked up because it is Seattle. Young ladies voice said "hello?....Hello?... Can you hear me now?,,,Let me turn up my headset...Is that better?"  I hung up but my phone immediately rang again. Woman said she was calling from John L Scott Real Estate. I hung up.
