First, my caller ID said "United States", instead of the city where the area code is located (Greenwich, CT). This is a good indicator that the number is fraudulent/ faked/ spoofed.
This was an automated robocall, saying: "Hi, this is Sharon, your Google AdWords Specialist..."
I pressed 1 to speak to an operator, but it rang and rang and never connected.
They called my cell phone, which is on the FTC and State of FL Do Not Call List.
