Myntra.com — product missing inside the package which myntra denied

Address: Gautam Buddh Nagar, Uttar Pradesh, 201301

I placed an order on myntra app of samsung unisex pink active wireless earphone on 17 may 2019 and for which i made the payment of 3126 by my credit card. The package got delivered next day on 18th may 2019, but when i opened it i was shocked to see that the product was missing inside, i received an empty box of earphones. I directly made a call to myntra support and informed them about the incident within 10 minutes, i got their revert on 22 may 2019, declining my claim. This is my worst experience with myntra, i'm a regular user of myntra since last 3 years still i got no proper response from their end. The details of the order is given below, please help me in this case as support is not ready to respond.
