State Bank Of India [SBI] — Iam complaining about the refund from Amazon not credit in my card

Address:

India

On 18.01.2023 I purchased an AC from Amazon using my credit card on EMI. (Total Transaction Amount as on 18.01.2023 was Rs. 33413.90)
and due to some technical issues I returned that item and refund processed by Amazon on 1 july 2023 of Rs. 25047.42
But Still no credit in my account, I have shared reference screenshot of refund reference number and email of refund to SBI charge back and nodal officer
Refund Ref Number :74332743197319683262907
But he said that as on date we have not found any refund from Amazon for Rs.33413.90 in your card account.

Hence, we request you to please share the communication mail from merchant regarding the transaction refund in order to proceed further.
Then I contacted to Amazon and they are saying the same to contact to SBI

Please solve my problem
