Bank Of Baroda — refund from amazon is delayed

I placed an order on amazon on 18th october, 2018 for ₹1278 and paid using upi through google pay. I cancelled the order then but money hasn't been credited to my bank account yet. Amazon customer care gave me the reference id:[protected] of the initiated refund from their end. I was asked to raise a charge dispute. Kindly resolve the issue soon as it is pending from many months.
