Indian Bank — indian bank refund related issues

Address:

Coimbatore, Tamil Nadu, 641014

My name is viknesh t v and i had ordered 3 products in amazon for 958/- on 14.04.2019 and after on the same day i cancelled this order due to personal reason. And on contacting amazon after a week they told the amount was initiated 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.
