Hi Kinga88,
Welcome to the Community!
Sorry you haven't received your Netflix code yet. I've sent you a private message (purple envelope at the top right of your screen) so I can get that sorted out for you.
The channel list will always display all channels, not just the ones available in your package. What you can do is set up the channels you want to see by setting them as favourites.
Just press Home, Help and Settings, Settings and then Favourite Channels. Here you can select which channels you want to appear in your favourite channels list.
Look forward to hearing from you!
Josh
