I can't cancel avast free trial

I’m looking everywhere and I can’t seem to find a way to cancel avast premium free trial. I entered my email address after I already started to accept the 2 month trial, I already uninstalled the software and got a new antivirus. It’s not appearing in the subscriptions tab and I don’t know what to do. I don’t have an Order ID and I’m worrying.

What isn’t working? What errors are you getting?
