New Facebook account alert in email; not on the website

Yesterday I received an email with the following information:

 

******* (child's name) has recently created new account(s) at the following Social Networking Web site(s):

  • Facebook



For more details, login to Norton Family website and click "Alerts" or tap "Alerts" from the Norton Family mobile app

 

 

However, when I login and click alerts, I can find no information on this alert. There is also no information on my mobile app.   How can I find out more about this new account?
