Amazon refuse return pick and deny refund amount

I ordered Vinod Roma Stainless Steel Saucepot from amazon. It came under 10 days return policy. When i tried to return, nobody came to pickup. I raised pickup 4 times after each cancelation i had to call amazon customer care and they keep telling me it will get picked up next day. After 2 weeks of back and forth amazon told me they had done internal investigation about the issue and reached to a conclusion (which they cannot share) that they cannot do any refund / return / replace on this product.

Amazon keep giving false information that they have spoken to delivery partner and he will pickup soon. No body came to pickup and the delivery guy just marked it as “pickup failed, customer refused the item”.
