It is possible to enter subscriptions to a given streaming service both directly with the channel and through a third party like Roku, Amazon, Hulu, etc. You or someone in your household may have inadvertently taken out multiple subscriptions to the same service(s).
Log into https://my.roku.com/account/subscriptions. Any subscriptions you have through Roku will be shown and can be cancelled there, which will prevent their being auto-renewed at their next billing cycle. You will continue to have access for the duration of your pre-paid subscription period.
