Hi @anghvo,
We're sorry to hear that you're having this experience. I can understand how that may be frustrating.
Please be noted that Roku is only assigned by Hulu to collect the payment and all subscription management is solely handled by Hulu.
For further assistance with account and billing-related issues, it is more effective to reach out to our support team or directly here for your 'Account or billing' issue, here: https://support.roku.com/contactus. They will be able to further assist you.
Thanks,
Mary
