Just saw on another website that this number might be trying to sell home security stuff.
We've gotten several of these types of unsolicited robocalls in recent months.
(314)932-0064 called today, 2:00 pm. No message left. I've gotten a few calls before. Called back the number, a male voice says "Thank you for returning our call regarding the expiration of your vehicles warranty. Press one if you want to hear about your options or 2 if you wish your name to be removed from our list." The extended car warranty fraud was very big a fewr years ago, with several St. Louis jerks going to jail and getting hefty fines. Looks like somebody has revived this fraud - my vehicles warranty expired 7 years ago so it's clear that these crooks are cold-calling anyone.
Block them - they're scammers.
