Called again 5 18 2015 and I answered because it said it was from Customer Service, and were are expecting a call from something we've bought. Nobody said a thing.
voice recording claiming they had tried to reach the "business owner" (on a personal cell phone) several times to claim a google+ account. Didn't wait around to see what the scam was.
Business line, these calls are all day, several times a day, and different numbers almost every time.
"Hi. This is Kate, your Google Plus......" I hung up
