No one on this forum can cancel it for you. If you go to your Roku user account site, you can see any subscriptions you have through Roku and cancel it there.
But I have a hunch you aren't being billed by Roku, regardless of what your CC bill says. That price seems way too high for any subscription service available on a Roku device, although I do see that YES is pretty expensive.
Once you log into your account, look to see if there's any such subscription. My guess is there won't be one. That means your CC information has been stolen and the thieves are trying to steal from you. If that is the case, you must immediately contest the charge and ask your bank to cancel your card and issue you one with a new number.
If there really is such a subscription on your account, you must have subscribed to it, perhaps unknowingly, but just the same it's legitimate. Cancel it right there on your user site, then contact Roku support here to see if they might be able to get you a refund. Normally Roku does not/cannot refund a legitimate subscription, but there might be some exceptions.
