Roku 4400 no longer supported

Roku itself has no subscription fee.  What specifically are you paying for?  There are subscription services on Roku, as well as non-subscription/no-fee services, so you can pay as much or as little per month as you choose.  Ie: $0 per month is quite possible if you’re willing to watch commercials.

You can subscribe to different services through Roku, and the charge statement would indicate a payment through Roku. But first, you need to log into your Roku user account (https://my.roku.com) and check for any subscriptions through Roku. If you find something you don't want, you can cancel it right there, and you won't get any future billings. You can't get any refund, as it was an authorized subscription (even if you didn't realize you did it). 

However, what if you don't see anything listed on your Roku user account? If that is the case, you have been scammed, but not by Roku. Thieves have acquired your credit card information and are submitting bogus charges and using Roku's name to try to make it look legitimate. So check your user account carefully, and if you don't see an authorized subscription you need to take action. First, contact your credit card provider and contest the charges. Then, ask them to cancel your CC and issue you a new card with a new number. The scammers have your information and will continue to attempt to falsely charge you, so that card needs to be replaced.
