I am ag. I have ordered new digital av adapter.

(Product description - new digital av adapter for ipad 4 pro air mini iphone to tv for iphone 5 5s 6 6s 7 7 plus to hdmi hdtv and vga + audio converter. Sold by: cart2india - online. Inr 5, 079.00.)

I received a product delivery on december 16th, 2017. When i tried to use it on december 29th, ipad pro didn't recognize this adapter. I doubly checked this by consulting local apple store executive next day. When it is confirmed that i have received a 'useless product', on december 30th, i filed a claim for return & refund (Within 14 days of delivery of product).

In return, i received inconsistent replies from amazon india about denying claim.
1. Initially, reason for denial was given that 'i have opened a product'. When i asked, "how would customer know about non-working product without opening it?"
2. When amazon india didn't have answer for my this question, another reason came. 'late claim filed' (Not within 10 days).'
Nobody uses av adapter everyday. When i got first opportunity on december 29th, i tried to use it.
Now my basic question is "who is responsible for selling non-working/useless/defective product?"

Amazon india has unilaterally closed the claim without answering my question. Instead of accepting a legal responsibility of selling a non-working/defective/useless product, they are shrugging off their basic responsibility of good selling practices by hiding behind inconsistent technical excuses. This is as good as any other con-seller. I have lost trust on amazon india.
