Indian Bank — Refund__not__credited__into__my__account

I made a payment to Amazon, but somehow my payment failed and the money was debited from my account, as this was a failed payment i was supposed to receive the refund but that never happened. When contacted to Amazon customer service they said that the bank from it's end is responsible for this as amazon had already initiated the refund process.

Date of Transaction: 14/06/2022
Amount Debited: INR 700
Reference Number(Given by Amazon):[protected]
Amount to be Claimed: INR 700
