Ekart Logistics — Cheap and wrong product delivered

I had ordered Adjustable fit cargo pant-Black in small size on 18-Sep-2023 which amounted Rs. 899.
I received the product on 27th September and by paying Cash on Delivery of Rs. 899. But it turned out to be very cheap green leggings.
So, I request for refund of the amount or replacement with the original product. Pls consider my request as soon as possible.
