This is a scam company called 29prime.com running a "Press 1 campaign", calling pretending to be "contracted" by Google.com to update business listings for Google Places Local and Google Plus. They are attempting to get ownership of your Google Places account by means of a phone verification to screw you out of your account by boasting they will "update your location, phone number, etc"

Do not give these criminals any info what-so-ever, especially do not do a phone verification with them in any way.
