Attention business owner, your Google Plus listing is only 50% complete, blah blah blah. They claim to be from Google but they are not, don't fall for their Scam.
Called today, didn't answer, no message. Pretty much any local number that has +1 in front is calling via VOIP, or through some other blocker to hide the location of the call. Moral of the story: don't answer unknown numbers. If someone is looking for you, he or she will leave a message.
