Re: How to get my refund and cancel my subscription
@Andrewnconstanz Almost all subscriptions are nonrefundable. If you purchased through Roku login to your Roku account on a computer or phone and cancel your subscription. The amount should have been obvious when you subscribed so getting a refund may be difficult to impossible. If the subscription would not work that is a different situation.
