Where do i find my payment info in avast

Hello. I was using avast free and i signed up for a 2 months trial with premium feature. i want to cancel before it charges me. How do i do that ? In my avast account i don’t know where to go for payment info and remove my card. In my avast account it shows 2 subscriptions : avast premium security and avast premium cleanup. i want to get rid of both of them due to financially problems. HOW DO I DO THAT ??? i am looking for over half an hour and nowhere i can find this. Every time i try to contact support it asks me for order id. I don’t have one. i just clicked on the link avast showed me…so please help me out to cancel this before the time comes to charge me. Thank you
