State Bank Of India [SBI] — charge dispute refund never process

Sir, i am abhishek kumar, having a account in sbi, i have a refund from amazon, on 17/10/2019. But still my account has not credited by amount.
I have called the state bank of india customer service many times but nobody resolved the problem. No action is being taken. I also raised issue on cms.

I have confirmed with amazon and they have successfully processed the refund.

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.

The reference number for the refund is [[protected]].
