Myntra.com — product delivered but they declined my claim

Address:

New Delhi, Delhi, 110058

Hello,
I placed one of my orders on myntra on 20th september 2019. It was a mango tan tote bag and a mango pink top. The package was delivered to me on 22nd september 2019 and because it was a cod order i paid the total amount on receiving the package which clearly mentioned that it contained both my items. But on opening it, i found that the bag was missing for which i immediately called the customer care as i’m a very old customer of myntra and knew the procedure. They immediately took my complaint and asked me to wait till 25th september 2019 which i did but only to get an email saying that my complaint has been declined. The mail read as below

This e-mail is with regard to product "mango brown solid tote bag" pertaining to order number *

I understand your complaint regarding the refund of the product and apologize for the inconvenience caused.

Post checking your case, i regret to inform you that your claim for the missing product got declined hence the request for refund cannot be taken.

Wish you have an excellent day ahead.

I immediately called the customer service again but after talking about 45 minutes with 3 senior executives i was only told that nothing can be done now.
Please help as i’ve really lost my money on that bag which i don’t even have.
Attached is the photo of the mail i received on 25th september 2019
