The free Fing app, available for Android or iOS, will tell you the internal IP addresses of all the devices on your network.
Failing that:-
What make and model of TV?
What make and model of phone?
What app?
How does Now come into this?
In general, you can pair the Roku app with a Now or Roku device that is already configured, but you need the physical remote to start from scratch, or start again after a device reset.
However, I’m not sure if this is what you are asking about?
Set a Payment PIN on your account so that no-one but you can buy memberships on it.
Check your bank accounts monthly for any other unexpected payments to Now.
That way you can at least nip them in the bud, while you and Now figure out whose fault they are.
