Amazon India — Wasted my whole 2 days and at last I didn't get my product

Hi,
I have order mobile IQOO z3 from amazon sale on date 16-jan-2022, have total
amount 10, 940 rupees with exchange one of my mobile honor 7x,
and it have to deliver on 21 Jan, but due to amazon fast service,
It come to me on 20 Jan, so i request him to come next day evening which is 21 Jan actual delivery date
I requested him because I don't have mobile(Honor 7x) at that time for exchange.
and delivery partner came to me on 21 Jan morning, as I don't have mobile in morning because I asked him yesterday only to come to me in evening, so he refused me, and told me
I will not come again with rudely behavior.
So, I connect with amazon team and told him whole delivery scenario,
and amazon team ready to reschedule my delivery.
so I asked him to reschedule on Sunday(23 Jan), parallelly with one more order which have to deliver on Sunday.
And amazon is ok for this,
but order did not delivered on Sunday, as I waited for whole day for same,
and connected with amazon many times also because of same i haven't gone any where,
so at last i connected with amazon team again
and amazon promise me to deliver it next day,
as i have to go for an office work, but because of mobile i wait for whole day again. And same thing happened next day on 24 Jan
Order didn't delivered to me.
at last i called amazon and he promised me to deliver my product next day on 25 Jan surely.
so on 25 Jan
I checked my order history
and it shown to me that your order get returned by delivery partner
So i connected with amazon
and he told me that you can reorder that product
and whatever the difference amount you will see on purchasing,
will be send to me on my amazon pay wallet, and the difference amount is 6000 rupees
and amazon refused to pay that amount
amazon only agree for 4000 rupees

but now,
things are not for money
they have wasted my whole 2 days and at last i didn't get my product.
So i need a proper clarification and solution for all my problem.

Thanks and regards
Venkatesh prasad Gupta
