I would like to ask why I received this email and this billing?
Thank you.
Assuming that your subsription is not due for renewal, this would be a scammer trying to get you to call that phone number so they can 'refund' your money. What actually happens is that if you give them your banking information, they will withdraw from your account, clearing you out. You should just delete the email(s).
You can check the email address of the sender against this information. Is this email from Norton legitimate?
