@FancyShantzy your post tells us nothing. Have you checked your Roku user account (https://my.roku.com) for any subscriptions you've made through Roku? The Warner Media charge is usually for HBO Max.
If you do not see a matching subscription under your user account, Roku is not billing you. It has been explained numerous times in this thread. If it's not a listed Roku charge, you are being scammed and you need to contest the charge with your credit card company. Chances are good your CC information has been stolen, and you should cancel your card and request a new one.
