Amazon India — Automatically cancel the order

I have order samsung s20fe 5g phone from amazon. It's estimated delivery was on 24th July 2022.
First of all, they haven't got any intimation and reschedule my order date to 25th July 2022
Secondly, Suddenly on 25th July, 2022 I see the status of returning to seller, in this case as well they hadn't notified to me.
Also, still i am waiting to get my refund in my original payment method.

when i have discussed this issue with their customer executives multiple times, they don't have exact reason or answer for the same. Also, they are blaming me that you have returned the parcel. if they haven't contacted me, how could I return it ? Also, denied to place new order with same price which was earlier.

I need my money today only and please help to get it in my account/credit card today only.

I have also taken multiple screenshots for the same. so, if necessary i can provide those as well.
