Amazon.com — Refund not received

I have ordered a bean bag of 2099 rupees (order no.[protected] from amazon through indian bank debit card. The order was returned and amazon has initiated the reference no. - 05134041057031277977608 but the refund is not done. I have been contacting the customer care of amazon about 4-5 times in more than 15 days now. I was asked to look for the bank statement and i have already done it and it shows no such credited amount in the bank. Then, i was told that the reference number for the refund is not initiated yet. And then after contacting to the higher officials amzon has provided a reference number and i was told to wait for 3 days. And still i have not recieved the refund amount. I have even visited the bank(Indian bank) regarding this with the reference number as asked by the amazon customer care but they do not have such facility.

Kindly do the needful.
