Central Bank Of India — Refund not credited

Address:

Lucknow, Uttar Pradesh, 226201

I have made a transaction through my central bank debit card on amazon on 5th Apr 2017 of INR 11, 999.00 . Later i cancelled the transaction but didn't get my refund as of now. When i contacted Amazon about the same they told they refunded the money on same day. After many follow ups and waiting for a month they provide reference number 311110 and told problem is from your bank end. When i contacted my branch and their customer service they didn't provide any status of my refund. After 10 days i filled transaction dispute form, my bank neither provide refund nor status of refund.
I also approached nodal officer for the same after a long time my branch manager wrote a mail to me and ask for transaction number. But how can i provide the transaction number. Currently i am living in Noida and only for this issue i visited Lucknow my home branch two times and after that my issue is not resolved.
When a customer made a transaction trough any bank they send a 14 digit transaction number in a message on customer's registered mobile number. But in central bank they didn't send a transaction number at all and how can i provide transaction number if they didn't provide to me. I want my refund with compensation because from last 1 month and 8 days my bank is misleading me and not providing my refund.
