Myntra.com — received the wrong dress and they are unwilling to take it back - duplicate product codes used

Address: Bangalore, Karnataka

I have had the worse experience with myntra customer service as per the attached emails against my order no. 4775201. I had placed an order for a navy blue striped dress as per the attached image and received an olive green striped dress. They said as per their internal verification they have sent the correct product to me. As per my attached screenshots of the tags and products i have shared proof that product no. 9267143 has been tagged wrongly by their website as a blue striped dress. The product - green olive dress has the same product tag. As per the attached proof i would like the wrong product to be returned and to get my money back!!! They are unwilling to accept their error and penalising the customer instead.
