Thanks for your post.
Sorry to hear about your experience with the Roku Voice Remote. To clarify, you have tried all the suggested troubleshooting steps here: Fix your remote. If you still have no luck after the steps, kindly send us here your Roku device serial number to which the remote is paired. Its serial number is printed on the bottom or back of the device.
Once we have this information, I'll be able to pass it along to our Support team who can assist you further.
