Netflix setup to someone elses email by mistake, and cant remember password

Question

I just registered to netflix on my appletv and missed the word "the" off the start of my email address, but registration was successful, its linked payments via my apple acct to somone elses email, and I can't remember the password.
I know it worked because my tv logs in, I can watch films, but now can't access it on any other devices
How would I get the email address changed when I don't know the password and can't access password reset emails?
