Account problem/ invalid email used for avast subscription

Hello, i am writing out for help. I subscribed recently avast antivirus premium, but in the order, i used my email badly, i gave some bad digits into it and the order went on email i dont even have access to! What should i do? Will the subscribtion end itself automatically if i won’t pay it after 2 months?! (ps: it was 2 month free trial)

Same, I cannot contact anyone by chat or phone number, I don’t have and they’re no where to be found, I think I have 2 different accounts?
