Ekart logistics - Return product not being picked up

On the *th of April I had ordered a pair of Kook N Keech "Men White & Black Striped Running Shoes" from Myntra which was then delivered on the *th of April, **** by Ekart Logistics, Hooghly. Upon receiving the order, I unboxed it about an hour later and found that the entire sole area of the shoe was torn and used, since it had distinct dirt spots on it, plus there were faint patches of dirt on the main stitching on the side of the ankle. The complaint ID with Myntra is IN********************. A return was approved by Myntra, but Ekart logistics pick up agent, Rohit, after speaking to the Chandannagar (West Bengal) warehouse manager Pratap/Rahul (I don't remember the name) and said that they cannot receive the product as the product image that the delivery exec received doesn't match with the product. My question is, how will a damaged product's image reach a delivery executive if I was told that no image was required to be sent? And even so, a damaged product cannot look the same as the original product, BECAUSE IT IS DAMAGED!
I raised another complaint, where currently nothing is being done either by Myntra or Ekart... every day I receive pick up text messages, and just * hours later another message comes, that "your pick up has been cancelled"... it's been a week now since I've been trying to return my product and get a refund, but no one is picking up my product...
I just have an open complaint ID in the myntra application - IN********************.
Somebody please help me with this.. it's not a matter of the money, it's just Rs ***, but it's a matter of the unfulfilled promise that Myntra/Flipkart usually assures to deliver it's customer...
