Subject: charge dispute "refund never processed"

Dear sir
My account number is [protected] and name is gaurav gupta. I have purchased an item from amazon online shopping site and done payment through my visa debit vard on 1 october 2019 but i cancelled the item immediately due to some reason but that amount of rs 13399 not issued by the sbi bank service.
A refund of rs 13399 rupees was successfully processed on 01 october 2019 to my account by the amazon india online shopping site but this amount should have been credited to my sbi account by now, but i have not received the refund till now 10days already over.

I have called the state bank of india customer service and also emailed the state bank of india main branch all the details many times including the unique transaction reference number but nobody has replied or resolved the problem. No action is being taken.

I have confirmed with amazon and they have successfully processed the refund on 1 october 2019 at 8:54pm. They provide me the reference id of the transaction - 281377

Kindly go through the charge dispute emails, locate the pending refund and follow the path back to amazon's payment processor to locate the refund.
