License renewal

My license according to my records is due for renewal on 2020-01-07.
I have received 2 e-mails perporting from AVG, one quoting £52.99 due 30 days from the date of the e-mail (23/11/2019) and another on the same day quoting the renewal date in 2020 shown above  amounting to £79.99.
Can you explain?
