Expiry of credit card

Hello Ant,
Let me explain this clearly. Yes, your AVG TuneUp is up for renewal and the expiry date of your payment card is showing as 10/2018. That's why you received that expired notification. Please click on "Renew now" option or log in to your AVG MyAccount to renew it manually using your new card.
Else, you can contact our sales support http://avgclick.me/AVGsales via online chat to renew it with best discounts.

A routine letter from AVG advises my credit card will expire and affect my subscription renewal. However "expiry" on my VISA card is given as end of June 2021.
