Received a call this AM from this number - CID just says Seattle - no message on machine, but every 10 minutes after got calls from "private number, private caller" who then left part of a cut off message about a walk in tub. Ridiculous - go soak your computer dialer in that tub!
Definitely a robo-call, most likely not actually from Seattle. I don't answer these, but i won't let them go to VM either. I simply pick up on the first or second ring and then immediately hang up, so that the call gets disconnected with no further feedback from my end.
