Amazon India — Financial and Mental Harassment

Hello this is for my Amazon order number #7566.
On 25 July 2022 Amazon showed me an exchange offer on their laptops which provided me an extra discount of 5000 on the exchange value. I ordered it and the delivery boy came on 31st July 2022, he checked my device and asked me to repair couple of things otherwise it will be cancelled and asked me to reschedule it for a week I did what he said, it got rescheduled to 6th August 2022 and I repair what he asked me to, it costed me Rs. 5000 to fix everything. i got it done on 4th August, then I asked amazon to send me the product earlier because it is in their warehouse and they said it will be done tomorrow, nothing happened then I went to their warehouse they said it was returned to the seller couple of days ago. i complaint on amazon customer care so many times but they assured me that i will get it by 6th August 2022, then today it got cancelled now amazon is saying that it was attempted to deliver but your calls was not connected and telling about their policy. They have no records in their database that an attempt call was made, no records of mails for attempt but they saw it was attempted 3 times on the same day 31st July, now their policy is that the next attempt is made the next day how can they attempt 3 times in couple of hours? And their customer support team rudely disconnected my chat.

My 5000 rupees are lost which was advised by their delivery team, the have mentally harassed by not listening to my complaints.

I need the following clarifications from them:
1) Showing me the records for attempted deliveries that were made by SMS or email.
2) If delivery attempts were failed on 31st and due to that it was cancelled then why it kept showing me till 5th August that it is rescheduled and will arrive tomorrow.
3) Why their delivery partner asked me to repair the device which costed 5000 rupees.

I need a recovery of my financial loss and an strict action for the mental harassment by their customer care team; some of their names are Saddam, Amena and 5-6 others.
