Returns aren't accepted for Surface devices in particular?

No, returning a purchase is not a concept that exists in India, whether for electronics or clothes or other things.

That's false. I've returned a number of items to Amazon India, Myntra and other online/offline stores

Not true. See my post at https://news.ycombinator.com/item?id=14415675

Try walking into a random shop and asking if they permit returns.

That's incorrect. I returned a MacBook to Amazon.in a week ago. There was no fault with the piece I received, I just changed my mind about it. I've returned other products to Amazon too, like a phone that was slightly defective and other electronics.

I've spoken to people who sell products online on Amazon.in and other marketplaces. All of them accept returns and write off the losses on those as overhead of doing business.

That's not true.

10 Days; Replacement only

Not eligible for return if the item is "No longer needed"

I've confirmed this with Amazon. You may have been successful, but nobody should buy a product assuming they can return it, when the policy says otherwise.
