Amazon India — Refund or return the product

I have not received the refund for Levi's Men's (511) Slim Fit Jeans[protected]_Blue_36W x 32L) which was picked up from my place on 27/7/2021.

On calling the customer care, I am told after 1.5 months that the product is not matching and it is at the fulfilment center. I totally disagree with the fact that the product is different because the courier person had verified the jeans at pickup and also because the only place I bought the jeans was from Amazon.

The refund status says that the product is still in transit!!!

I do not have the refund nor do I have the product. Look into the matter on an urgent basis.
