State Bank Of India [SBI] — Amazon refund initiated but not received

I ordered a product from Amazon.in on 28/05/2021. I received it on 31/05/2021. But I wanted to return that product because it has some issues. So I placed a replace and refund order on the same day on which I received product. I received Refund Reference Number as[protected] by Email from Amazon. My product is picked up by Amazon on 02/06/2021. Now there were 7 days passed but yet I have not received any messages of my refund. I ordered product from my mobile number but I entered my father's bank details during refund procedure. Please understand my situation.
