Who called from 2064456643

I have no idea who this person is and I don't know how they got my number.

Received a call from 206-445-6643 today. Don't know who this person is and don't know how they got my number. They hung up before I answered.

Call from 206-445-6643 to my cell, no message or text. What is the point of this?

Received call from 206-445-6643 at place of employment.  Answered the call and they hung up.  Received the same automated messages to press "1" to opt out of future calls but the problem is they didn't request the number I was actually calling about.  Seems like another computer generated scam/harrassment.

Just called my work twice and left no VM.  So annoying.
