Bank Of Baroda — refund issue I'm complaining about

Address: 65/1 MAHARSHI DEBENDRA ROAD, Kolkata, West Bengal, 700006

I ordered shoe from amazon on 28th september and i returned it on 30th spetember and i was about to refunded the amount of that shoe. But today is 11th october i got no refund in my bank account. Amazon provided a reference number and i called bank of baroda customer care they said no amount has been refunded by amazon. I called amazon customer care too they said refund has been initiated on 30th september and they have provided reference number and they are claiming without initiating refund they can't generate reference number. I've go no refund.
