State Bank Of India [SBI] — Amazon initiated amount but did not credited

Hello sir/ma'am,
I had ordered a product from amazon and later returned it due to some reason therefore the amazon has supposed to transfer my money. In the process they initiated the amount on 17 Nov 2021 but still i did not received the money back in my account. when i have contacted with amazon customer support they told me that its now up to your bank side process because they have done payment to the bank. they also provided me the refund reference number which is 997178
i am also attaching the image of mail received from the amazon side.
