Blue Dart Express — product not as same as advertised.

I received my parcel on 13 dec 2018, my tracking i'd for the smart wrist watch which i have ordered is [protected]. The watch which was ad retired is completely different from the watch which was delivered. I have bought the watch for inr 2100. So i am not satisfied with the product, hence i want to return the product amd expect a refund of my money as early as possible.
