Bank Of Baroda — refund is issued by amazon but the bank of baroda says that it hasn't credited to my account

I had ordered a product from amazon but i returned it so i was supposed to get a refund of 710 rupees within 5 days but because of the holidays on independance day and afterwards it was delayed.
Amazon agent on being contacted by me said that my refund is issued by the amazon and is being delayed by the bank but when i contacted to the bank their executive said that the refund amount is not issued by the amazon.
