Flipkart — Ekart Logistics pickup person not accepting product for return

I have received a damaged product (rat eaten shoes) i had generated the return request right away with all the images proving that i have received the damaged product. Now due to some application problem the pickup agent is not accepting my product. The Wishmaster of Ekart rejected my return request multiple times with the same reason as I have requested return for.
