I need help, no one has emailed me back and I have not been able to talk to anyone
You can navigate to your Roku account here to see your subscriptions after you login to your dashboard.
If you have any disputes or questions then you need to navigate here and select the Billing options from the dropdown menus.
When you are in your dashboard, enable a PIN which will prevent any future Subscriptions or Channels from being installed without you first entering your pin on a popup box on your Roku Device.
Also, seems some people have been receiving fraudulent invoices for services. Check your subscriptions and include any such info to that Roku support contact form.
