[Resolved]  Punjab National Bank [PNB] — refund not reflected in my account

I had placed an order with swiggy on April 17 2019 through Amazon Pay using Pnb Rupay debit card.But due to some problems swiggy cancelled the order and refund was initiated by amazon on the same day. Amazon told me that i would get the refund by 29 April 2019. But i did not get the refund. So I contacted amazon again. They gave me refund reference number and told me to file a charge dispute with the bank.On contacting with Bank they told that they do not know about any charge dispute and they can only check account balance.So I kindly request you to ask them to refund my money as already 14 days have passed.I am providing my details as below with screen shot from amazon.
