I have a Roku Television that I set up under the wrong email with all of my info including bank charge. I wanted to close this account and remove my bank info for it is wrong. Need someone to contact me. I have been trying to resolve this and another matter with showtime billing me for a trial subscription that I want to end. All on the Roku account which is wrong
Try contacting https://support.roku.com/contactus/ and choose the "billing or account problem" option. Use the same account you're using on this forum when you're asked to sign in.
Even if the email account is not a working email address for you, at this point it is only a login name for that Roku account. As long as you know the password you set up when you created the account, you can still log into it at https://my.roku.com by using that email address. Once logged in, you can:
To then connect your Roku to the correct account, do a Factory Reset via Settings > System > Advanced system settings > Factory reset. You'll then be setting the Roku up all over again from scratch, including linking it to your desired existing Roku account if you have one, or create a new one.
