Hi, @ubutme
Thanks for posting, and welcome to the Roku Community.
We appreciate you sharing your concern about canceling Disney+ on your Roku account, and we're here to help.
To manage or cancel your Disney+, subscription, even if you're billed through Roku, you must contact those streaming services directly. Roku processes the charge, but Disney+, Hulu, and Sling TV handle management of the subscription.
You can contact them at Disney+ Support
We hope this will be sorted out soon, and let us know if you have further concerns or inquries.
Thanks,
Kash
