Sorry to hear this 
I got the same email and for a second it really confused me. It looked like it was an authentic Stellar email. I knew the stuff they were claiming wasn't true, but I can see how it would be easy to confuse someone.
You did great by reporting the phishing url to google. I did the same.
If you live in a country where police has resources to investigate this kind of crime it's maybe also worth reporting it.
