Canara Bank — Requesting to look after refund.

Amazon initiated a refund of 121.60 to my Canara bank account on[protected] which is to be reflected in my account within 4working days but I didn't happen and after talking to amazon customer they told me that we initiated a refund and this is your reference number: 30005410030364192649637, after receiving reference number I contacted Canara bank customer care for which they told refund is not initiated from amazon side and again when I contacted amazon customer care they clearly mentioned without initiating refund there wouldn't be any reference number so please talk to Canara bank customer care.
