Number didn't look familiar in caller ID, so I declined it ... no V/M message left.

Illegal number used by SCAMMERS. This is a scam trying to steal your information and Money. THIS IS A SCAM!

Recorded robocall. Hung up after the recording started.

Caller ID shows: Sanford, FL 321-832-7637
These scumbags/criminals claim to work for Google but they're NOT Google employees and are NOT authorized to make these fraudulent phone calls.
Again, these con artists are using a spoofed number, and they care less about the worthless DNC list...
BEWARE: These people are criminals who will try get your personal information and steal your identity.
The DNC list is simply useless and you should NEVER answer these calls period!!!
You should also consider buying a phone blocking device which blocks area codes and eliminates most of these trash calls.

Criminal TeleScammers.  Sanford Florida area code.
