Flipkart — Delivered Wrong product and not returning the product not refunding my money

I ordered LEVI'S pant of 36 size online in Flipkart App with order ID OD[protected], but they delivered 34 size. I requested for return of the product on 28/01/2023 and refund my money, but the seller is not responding since then and Flipkart also not taking action against the seller. Both are not concerned about the customer. They are looting the public/customer money by showing one thing on Flipkart online platform and delivering another. So please take the action against the both seller and Flipkart not being responsible for there actions.
