Supposedly I need to confirm my google business listing... No business here... Scam

Dead air when I picked up, but all 818-210- calls we've received have been about Google listings. I've received Google "partner" from all the number listed below. In our business we get legitimate calls from all over the US but at this point I'm blocking all calls from 818-210-* -- and all of these numbers have been blocked as well. This list of Google "Partners" who call and call and call is FAR from complete ...

Recorded message from the "Google Verification System".

No message. I've saved this number to my caller ID under "scam" so if they call again I'll know to ignore it, or answer the call and repeatedly press the # key to signal the robo dialer that it's a nonworking number.
