I had ordered a trial subscription for a FOX channel through ROKU and need help to cancel

Hello, thank you for using Howly. I’ll be happy to help you out! May I ask your name?

Nice to meet you, *****!
Do you currently have access to your Roku account?

Ok, good.

To cancel a subscription managed by Roku:
https://my.roku.com/account/subscriptions <<< Visit this link and log in if prompted.
Locate the channel under Active Subscriptions and select Cancel subscription.
Select a cancelation reason to complete the process.
Is everything clear with the provided instruction?

I’m glad I was able to get that sorted out for you. Before you go, is there anything else I can assist you with today?

You're welcome!
