Hi, @jess1132.
A warm welcome here in the Roku Community!
We understand you're facing issues canceling your Hulu subscription.
While Roku processes the payment for your Hulu subscription since your credit card is linked to your Roku account, Hulu itself manages and controls those subscriptions.
Contact Hulu Support Directly: They'll be able to walk you through the cancellation process and answer any questions you have about your subscription. You can reach them through https://help.hulu.com/.
We hope this clarifies the process. Don't hesitate to ask if you have any further questions about your Roku device or Roku account.
Regards,
Emman
