Flipkart — I had ordered a Misfit trimmer for Rs999 on 9th dec and got the wrong product delivered

I had ordered a Misfit trimmer for Rs999 on 9th dec and got the wrong product delivered through bluedart the product was COD and paid Rs999 on receiving the product,

After opening the box I found that the product inside the box is different from what I ordered
I have taken photos and videos of the product which I have received and I raised my concern that the app is not showing the Product delivered and when i complained about the same, instead of remarking it as delivered, they extended the date of delivery so that i can't even raise the return request .

This is fraud behaviour from Flipkart
I have lost my money and I haven’t got the product
I want flipkart to give Me the product which I ordered or return my money.
