Flipkart — They gave damaged product they are accepting the return request

I have bought LG refrigerator 185L in flipkart which given by seller IWQNBecommerce. When it got delivered, there was a dent below the product. Called LG support to come and check. They suggested we can't do anything, please request refund or replacement. I have filed the request on 12th jan and today is jan 26 there is no update on that. I have been calling there support team daily and they will say we are checking and back end team will contact you. When I received the call from them no one spoke from other end and they closed the request saying I didn't respond. Flipkart is the worst customer service and dont ever buy anything on that.
