State Bank Of India [SBI] — refund not resolve

Address:

797001

Dear sir
I am writing this again as no resolution or action has been taken so far from sbi, that is
A refund of 29999 rupees was successfully processed on 18 march 2019 to my account by amazon refund reference # in[protected]. This amount should have been credited to my sbi account by now, but the refund is not credited to my account till now.

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 contacted my bank branch many time for the same but was told that they are helpless as this case should be taken up by the sbi customer service.

I have confirmed with amazon payment team and they have successfully processed the refund with the unique ref. No. As given above.
