Automated robocall saying something like 'Press 1 to verify your Google listing, Press 3 to remove your listing'... I didn't do anything and hung up on it. I admit I was tempted to press 3 as have been getting repeated, frustrating, and annoying automated calls from 'Google' lately...
Number called, rang a couple of times then hung up. I called back and it said it was the do not call registry calling me. Seems a bit strange that they would call me to have their number opted out. I think it's a number harvesting service. I need to do a bit more research.
