@stefanied2023 it has been covered numerous times in this thread. If it's a legitimate charge from Roku, it's likely for HBO Max.
If it's not legitimate, you can log into your Roku user account (https://my.roku.com) and check for any other subscriptions there. If there is something there you no longer desire, you can cancel it on that page. If you don't see any subscriptions on your user account page, you are being billed fraudulently, and not by Roku. You need to contest the charges, and consider cancelling your credit card and getting them to issue a new one. Fraudulent charges would imply your personal information is on the dark web, and they might continue using that CC information to steal from you.
