(update) I've gotten one call per day since I first reported this a couple days ago. Annoying that someone would waste their time doing this. I've gotten to the point where I just ignore it.
408-189-0769 keeps trying. They can't leave a message (like they would???) cuz the mailbox is too full from scammers.
Important calls go to another line :) Thanks for the posts here as to what these s**theads are!!
