Avast Premium Security - i can't cancel subscription plan

Hello, so i wanted to cancel my subscription plans - Avast Premium Security and Avast Cleanup Premium.
The second one is already done, but with the first one i don’t have a “cancel subscription” button on my profile page. It just says there will be next payment in march.

How can i cancel it? i can’t find any way to contant directly with Avast.
