Bank Of Baroda — i have not received my refund in my bank account. the amount has been refunded by amazon.

Address:

Jaipur, Rajasthan, 302006

I have not received my refund amount of rs7695 in my bank account. The refund has been issued by amazon on 12 may 2018.
The authorization refund number for the transaction is 202104. The bank is denying from the fact that there had been any refund initiated.

And amazon is saying that they have made the refund by 12 may. I contacted the bank customer care they are denying from this fact that this refund transaction number seems like useless for them. It has been 3-5 working days still no refund has been initiated.. Kindly see in this issue.
