trying to unsubscibe from auto renewal

I have been trying to unsubscribe from auto renewal but with little success Very frustrating even when i do access my account it shows the subscription is not active as far as when the date the program is to be renewed. Can anybody give contact email details for avast anti track.

Sales - Orders and Renewals FAQ - https://support.avast.com/en-ww/article/Alternative-unsubscribe/.
Scroll down to the “How do I cancel automatic renewal of my Avast subscription?” option.

I’m not sure if this also has a section for Anti-Track - Though it would appear so "Applies to All paid Avast consumer subscriptions ".
