Amazon India — fraud in name of internal policy

I purchased a food product, from amazon India and the seller sent me a product which has got a expiry date on Nov 19. When I inquired Amazon in regards to expiry, they told as per Amazon internal policy the food product should be above 60 days.But there is no mention of the expiry date in the product page neither it is mentioned anything in their return POLICY. I contacted the support and Amazon support inform me that the expiry date should be above 60 days, BUT it is only mentioned in their internal policy and cannot share a link. Meaning they hide their policy and ran away with it.
If Amazon wants to be transparent just provide a link where it is mentioned, amazon send food product till 60 days to expiry. Tomorrow the figure may come down to 30 days and 7 days. It is not clear at all and they sell out this expiry products in the name of FLASH sale

This is unscrupulous act and the company is turning out to be subterfuge. They hide their policy and ran away in terms of internal policy, its time to stop purchasing from Amazon.

Moreover whenever the seller sell using your platform then AMAZON is equally responsible for the product.
