I let it go to VM, and I played the message, and it was a robocall in a female voice, which the first part got cut off..it started with "part of your verification" and it gave this number to call back. I have no idea who they are or what they want.
Calls my cell everyday, never leaves a message. Called back and it rang like 10times then "the Google subscriber you are trying to reach..." Message picks up.. Annoying!
