Cancelling AVG TuneUp Subscription

Hello Teresa,
We are sorry that you've decided to cancel your AVG PC TuneUp subscription.
Auto-renewal service was cancelled for this subscription and no charges will be taken in future.
Feel free to contact us if you need any help.

I received an email that my AVG TuneUp subscription will automatically renew in less than 60 days. I DO NOT want to renew it…I want to CANCEL that subscription IMMEDIATELY. 
Unfortunately this subscription does not show up on my AVG account when I log in, so I am unable to see how to cancel it from my end. In the FAQs it is suggested that this subscription is tied to another email…I assure you, it is not. I just seem to be running in circles trying to find out how to cancel this subscription.
Please advise…how do I cancel my Tune Up subscription? 
Thank you so much for your help!
