State Bank Of India [SBI] — refund charge dispute with sbi

Website:

Amazon

Dear Sir,
Refund from Amazon for an amount of Rs. 999/- has been processed on 21.05.2019. Authorisation code for the refund is 213186. The refund is not credited in my account till now. Conversation with amazon regarding this from my gmail account is attached. The transaction was made with my SBI debit card for an amount of Rs. 1998/-. The remaining amount has been settled.
Please see a pending refund and follow the path back to amazon payment processor to locate the refund under charge dispute as 'refund not processed'.
I have also filed a complaint with sbi, Vikas Bhavan, but they refused to accept it.
