Bank Of India — I'm complaining about my pending refund

Address:

Satara road branch, Bharti Vidhyapith, Pune- 43, Pune, Maharashtra, 411043

My name is suraj bulunge. I had ordered "toolscentre plastic 1020w paint mixer along with toolscentre paint mixer stirrer rod" of rs. 3410 (Three thousand four hundred and ten rupees) in amazon on 25 feb 2020 and after 2 march 2020 i returned this order due to personal reason. And on date 2 march 2020 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 bank of india doesn't have such policy. So please kindly respond to this complaint it's very urgent. My card number is ([protected]).
Thanks you sir
