@AliClarkW There is no basic, standard, or premium Roku service. There is NO CHARGE for using a Roku device. You can purchase subscriptions to various services such as Netflix, Peacock, etc....
If I were you I would open my Roku account on a phone or computer and change your password. Do not call any phone number listed on any website purporting to be from Roku. Do not share your phone number or email with anyone purporting to represent Roku. Again there is never a charge to activate a Roku device.
