HYUNDAI - Rear spoiler not attached with aura SX

Dear sir,
Today I have purchased a new Aura SX from Fairdeal Hyundai Dipatoli Ranchi.
I was shown two three Aura SX model during my visit.Each model was equipped with factory fitted rear spoiler and I was satisfied with it and paid for it in cash.
However after delivery I discovered that the rear spoiler has simply vanished.
When I complained about it, the manager Mr Rahul and Mr Keshav of Fairdeal, said that company has discontinued fitting of rear spoiler in Aura.
I just want to know whether Hyundai has since discontinued spoiler fittings or Faideal automobiles deliberately delivered an old model of Aura?
Another thing how can I be sure of model and manufacturing date of my car?
Details of my vehicle is follows

I request you to look into the matter and do the needful at the earliest.
Regards
