Who called from 8013857594

I never answer anything that says 'name not found'.  Caller hears part of my message, hangs up and calls several times a week anyway.  Who knows what they're up to?

Called at 1:45 p.m..  I did pick up. Sounded like some background noise then hang up. Really annoying.

Got another call from this # at 2:58 pm today.  Girl left some kind of singing on machine.  Sick of these calls  every day.

Another bogus call from this number.  I am beginning to recognize these numbers, so I don't answer...and they never leave a number.

No answer when I picked up.  Number "Not in service" when I called it back.
