Central Bank Of India — Refund from amazon not received in my bank account [protected]

I ordered a product of Rs. 283 from amazon on 23-dec-2021 with order id :[protected]

I cancelled the product and amazon has processed my refund of Rs. 283 and they told it should be credited by 29th dec 2021 and they provided me with refund reference number.

As it is already 8th Jan 2022 but i didn't get my refund in my bank account. I contact bank official, they are not helping me, they said it is amazon's mistake, they did not refunded. Same is the case with amazon.

Please do the needful and refund my amount as soon as possible.
