Amazon India — Incomplete order received and amazon not helping

My order no[protected] i ordered 2 neet books i.e. Physics and chemistry on 8 july 2023. I got the box in which there is only physics book and chemistry book is missing. On the box it has written 2 books but the box has the capacity to hold 1 such book only. I have raised the issue with amazon india they are saying everything is fine both books delivered but i challenge amazon to kindly fit 2 books in that box in which the book got delivered. So please refund my amount of 567 or give me book whatever is possible in okay with it.
