Flipkart — Received a fake 6TB hard drive

Website: Flipkart

Order id OD[protected]
I ordered a 6 TB hard disc from flipkart on 23rd April . I received the order in a card box labelled 6TB hard disc but inside the hard disc has a similar black case but upon checking its found its fake, later on i came to know the dimensions are also not according to a 6 TB hard disc. I contacted flipkart multiple times and the brand also seeking them to exchange the product but they failed to do so.
I suffered monetary losses amounting to 20 K and they clearly sold me a dupe and fake product which a common man can easily miss.
My request is atleast provide me with an original product for the money i have paid.
