Flipkart — Received wrong product and Flipkart rejected my refund

I have ordered Nike shoes with order ID - OD[protected]. I have received order on the 4th October, but when I opened Nike shoes box I found completely different company shoes which does not match with product specifications. So same day 4th Oct after 30 min I have raise return request.
In this return process flipcart asked me about my Aadhar card and product images. I have share all the details.
But on 10th Oct I got message that my refund has been rejected on the basis of courier service feedback.
Then I again open the refund request on 10th Oct. And again that request has been rejected

I have the recorded video of opening Flipkart package. Also after opening package I have already shown this wrong product issue to your courier boy as he was there next to my house. He said just raise return request.
