State Bank Of India [SBI] — Refund Initiated by Amazon but still not received on my bank account

Dear sir,

I have ordered a product from Amazon.in on 10 August 2021 but it was a defective product so I have returned the product on 20 august. And the refund was issued on 20august. As it was a cash on delivery order. So I have entered my bank details to receive the refund amount to my bank account. The value of the product was 899 rupees.

After some days I contacted the Amazon customer care and they told my that the refund amount was send from their end, and they also gave me a transaction 'reference number' and told me to go bank branch and check what was the problem.

I went to Sbi branch and they told me that no amount was credited and no amount is on hold. And they can't help me.

I am attaching some details. Please check and help me as soon as possible.

Thank you.
