Oh dear how frustrating for you.
Please look again at thepackaging as the remote is often tucked away in a little pocket either in the polystyrene or surrounded by cardboard.
If the TV is new and the box was sealed the remote is likely to be there, hidden somewhere.
I can feel your frustration, though, as the same thing happened to me about a little hand held saw that I bought. When I opened it there was no saw blade. Eventually I found it taped under a flap on the lid. It could so easily have gone to recycling.
