Help to cancel my old subscription

Antonio, The start of your next period would only be 2 days away!. You may need to check that cash hasn't already been withdrawn in view of this note within the AVG article "How to cancel automatic license renewal"…
Please note:
When you purchase an AVG subscription (formally known as "Continuing Protection Service"), the subscription will continue until you have cancelled it. Customers will be billed 15 days prior to the start of the next subscription period. Customers will also receive an email regarding the automatic extension of their AVG subscription, 45 days prior to the start of the next subscription period.

Hello Antonio,
Sorry for the inconvenience caused.
As we understand you want to cancel your Auto-renewal for AVG Internet Security which is going expire on 2/19/2016, is that right?
Thank you.

Hello, I have just bought a new AVG protection pro, but the subscription to my old AVG internet security is still on, and it will automatically renewed on 19 february. When I try to cancel it, appear this error: ErrorError Something went wrong. Product parameters do not exist.
Can you help me?

Hello Alan,
My cash hasn't been withdrawn, because the card that i used to pay AVG Internet Security is no longer available. I used another card to pay AVG Protection PRO, and now I am afraid that cash will be withdrawn because I can't cancel my Auto-renewal for AVG Internet Security.

Hello Gulam,
Yes, I want to cancel my Auto-renewal for AVG Internet Security which is going to expire on 2/19/2016.
Thank you.
