Subject: charge dispute "refund never processed"

Dear sir

A refund of 320.00 rupees was successfully processed on 20 august 2017 to my account by amazon. This amount should have been credited to my sbi account by now, but i have not received the refund till now.

I have called the state bank of india customer service and also the state bank of india 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

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.
