Myntra.com — Not refunding the amount after returns

Address:

North Goa, Goa

I had ordered ray-ban sunglasses. Returned it by DTDC since I found my lost sunglasses by the time these arrived. But Myntra is now saying that they did not receive the product. They received an empty case by courier. We had shipped it properly and shown it at DTDC. Myntra has signed and received the courier. But now they are saying that the sunglasses are missing.
