Flipkart — No return or refund of Godrej refrigerator from Flipkart

I purchased Godrej 223 L Frost Free Double Door 3 Star Convertible Refrigerator from Flipkart on 05/05/2023. Delivery was on 9/10/2023. The fridge had three dent on it's side. Delivery boy after contacting higher officials offered 20% discount as Flipkart gift card for accepting the product. I agreed. But Flipkart refused to give me the discount after 7 days on 17/05/2023. They initiated refund process on my request. Refund rejected without any reason, on 23/05/2023. So after 13 days of the delivery of the product, Flipkart customer care center informed me to contact godrej service center. They also rejected my claim as it is a physical damage.No I don't know what to do. It is pure cheating of Flipkart and the seller.
