What payment? There's no payment required to use Roku, only for premium services that may or may not be paid through Roku. You can view your subscriptions paid through Roku at https://my.roku.com/account/subscriptions . If you're paying for some service directly through the provider (e.g., Netflix, Hulu, etc.) then Roku would have no record of your payments. There's plenty of scams out there so if you paid a fee to set up your Roku or you're paying some kind fee to just use your Roku then that's not coming from Roku.
