Bank Of Baroda — refund from amazon not received even after amazon has already initiated the refund

My name is siddhant satam and i had ordered folddon multipurpose cloth storage cupboard of rs 2, 999 /-.in amazon on 18/7/19 and i cancelled this order due to personal reason. And on 21/7/19 amazon initiated the amount to my card but i still didn't get the money. Amazon sent this reference number
[protected] and told me to fill charge dispute form but indian bank doesn't have such policy. So
Please kindly respond to this complaint it's very urgent.
Thanks you sir
