If you subscribed to ESPN Plus through Roku login to your Roku account on a phone or computer. Check your subscriptions. If you find your subscription to ESPN Plus you can cancel there. If your ESPN subscription is not listed under subscriptions in your Roku account you subscribed somewhere else. You could have subscribed using Hulu or Disney Plus. Check those accounts if you have either account. If your account is not listed there call Disney at 1-888-905-7888. They may be able to help you. I have found Disney tech support very helpful.
