If you get an email with subject “Facebook Support sent you a notification” it is a scam. It is not from Facebook, but a company trying to steal your Facebook login and password. So ignore it.
If you use an antispam on your email your probably will not see it.
They call people saying they are from Microsoft, someone is trying to get the information from your computer and they can fix it. They are calling to get control of the computer.
This is fake company. You should not advertise them on Google.
Did you report them to Google Usha? Best to do so if they are fake, Google can only act if it received a complaint.
