Canara Bank — I have not received a refund

Address:

Canara bank Khadakpada Kalyan West

I had made an online payment for Amazon.in on 24th and cancelled the order. Amazon cancelled the order on 29th and initiated the amount but that amount is not reflecting in my account yet. When contacted Amazon customer service they told me that they have initiated the amount from their side. I spoke with customer service of canara bank but they are refusing to take refund reference number and further assistance and help. Kindly look into the matter as soon as possible. Thanks
