To all the people criticizing OP, 5 million people are victims of phishing attacks every year. This attack is more sophisticated than 99.99% of them. Cut OP some slack.
Emphasis mine.
Also, if a human called me and claimed to be working for Google, I would laugh heartily and hang up the phone. Google doesn’t even have call in tech support, why would they call you for something as banal as a compromised account?
A non tech person wouldn't know Google has bad support and is unlikely to call you, that a number and email can be spoofed, etc. And even if 99% didn't fall for it, just 100 calls gets the scammer a victim on average.
