Flipkart — Rejecting return request and not refunding my money

I ordered NIKE Air Max Impact 3 Basketball Shoes For Men Size 10 (Order no. OD[protected], Seller was RetailNet, I got totally different Nike running shoes instead. The order was delivered on 28th August, 2022 and from the same day I have been trying to return the product but Flipkart officials are rejecting my request. I have sent my Aadhaar card as well as all the photos related to the shoes received and even their customer support accepted the fact that they received it still nothing from them. Please get me my refund of 6, 310 rupees.
