Amazon — ordered cera b4512205-g kitchen sink and amazon sent wrong design and damaged sink.

I ordered cera b4512205-g stainless steel sink for my kitchen from amazon on 13 april 2019 and it's order no.[protected] for rs. 9440.
When i received the item it was damaged, i immediately placed the return request on amazon. Next day when amazon boy came for pick up he denied to pick up the item because its design was little different. He told me that you have not mentioned that it is different while filling return.
I called amazon regarding this and they told me to send images. I send them images and they put this return on 5 days investigation hold till 26 april.
They sent me wrong and damaged product. On the first look i found it damaged and immediately i placed return request, i didn't feel investigating it full for design difference because it was already damaged on first look. And it is still seal in original company poly.
Amazon should pick up this scrap and refund me full.
