This is not Google so under no circumstances give them ANY information or you will get ripped off for certain. Google will NEVER call you about updating a free listing they have absolutely no reason to do it...who in the heck doesn't about google? No one! They have no need to call us at all. This is a scammer from outside the US looking to rip you off.
This is a fake google seo people calling you, if you haave a free google business listing don't press 1 your business listing will be claimed to them they use phone system software to take over your business listing.
