@sagojanet, check your purchases at https://my.roku.com/account/purchases and your subscriptions at https://my.roku.com/account/subscriptions . If none are shown there's a good chance it's not coming from Roku. Keep in mind that just because a description of a charge uses "Roku" in it doesn't mean that it really came from Roku. For suspicious or unauthorized charges you should always get your financial institution involved as quickly as possible.
