Myntra.com — Damaged product received

I ordered Roadster lifestyle Co Women solid olive green jacket . The order was delivered on 26 Nov 2022 and had 15 days return/ exchange policy. I recieved damaged product the hat was damaged and there were white patches on the it. I contacted customer service many times and applied for echange request also. But they kept on declining the request saying they have sold the right product. I even attached the images for proof and after 15 days they said nothing can be done regarding this. I asked for refund but they kept saying now they can't do anything. I want my money back. That was a complete waste of money and very bad service from Myntra. Please look into this.
