Canara Bank — refund 123

This is dhanalakshmi. I have purchased product on amazon, due to some issue, i canceled and supposed to give refund of 499.
From amazon, i got mail that

"your refund of rs.499 has been processed successfully on 5/14/2019. The amount should reflect in your account by 5/20/2019.

The authorization code (Refund reference number) for the transaction is 932889.

In case you do not receive the refund within 5 business days, please contact your bank’s customer care and mention the above authorization code (Refund reference number). Please remember that you will have to call your bank’s customer care center and not visit the branch for this query.

Some nationalized banks may take more time than usual to credit the refund. If your bank is unable to locate the refund with the authorization code provided, please dispute the transaction as 'refund not processed'. On disputing the transaction, the bank will see a pending refund and will follow the path back to our payment processor to locate the refund."

Till now i didnt get my money. If i call canara bank customer service, they are not responsing properly.

So i request you to take proper steps to initiate my refund amount 499/-
