Amazon — Refund is not received

Website:

Amazon

I had ordered some products from amazon on november and cancelled it on the same day. Amazon has sent me a notification that refund has been processed but the amount has not been credited to my account yet. The refund reference number is attatched. I called canara bank customer care and went directly to the bank for resolving this but they did not help me with this issue. I request you to check the status and process the refund.
