was notified by a technisian that after 2 1/2 years of use, roku charges for the use of their services, It says I will need to pay 80 - 100 if I want to continue usung the serve. I thought roku was free?????????????
You reached a scammer somehow, perhaps by doing a net search for "Roku support" or something similar.
Roku does not charge for mere use of their system. There are things you can subscribe to and pay for through Roku, but they are optional.
But if you found the scammer's site while looking for help with a Roku problem, the place to get help is right here.
