Every streaming subscription with which I have ever seen, either through a third party like Roku or directly with the channel, is nonrefundable. You are pre-paying for a specified subscription period and it auto renews when that period runs out. When you cancel the subscription it prevents the auto-renewal but the subscription stays in force until the balance of the pre-paid period expires. These conditions are explained on screen and must be accepted when subscribing (you know, all that stuff none of us bothers to read at the time).
My advice would be to enjoy your current prepaid year, cancel your subscription before it runs out to keep it from auto-renewing, then sign up for your free subscription through Verizon when the subscription through Roku goes dead.
