Indian Bank — subject I have been mentioned below

My name is madhu prasad and i had ordered a book named "the prophet" of rs 88 in amazon on 31st october 2019 and i returned it on the same day due to some personal reasons. And on 31st october 2019 amazon initiated the amount to my but still i didn't get my money back. Amazon send this reference number[protected] and told me to fill charge dispute form but indian bank doesn't have such policy. So please kindly respond this complaint it's very urgent.
Thanking you
