Hey @mhoutz29,
Welcome to the Roku Community!
I understand how this can be confusing. Please note that the subscription started and was billed through your Roku account. However, the subscription account is managed by Hulu, so only they can assist with and process cancellations and refunds. I would recommend contacting Hulu support again for further assistance.
I hope everything gets sorted out soon for you.
Thanks,
The Roku Community Team
