Indian Bank — charge dispute on refund not processed

Address:

456, GST ROAD Mamandur , Kanchipuram district, 603111

I bought an amazon product worth rs. 987 through indian bank debit card from my savings account on 15th december 2015 and cancelled the order on the same day within few hours. Amazon has successfully refunded the money and sent me a urt number #30005493509349001647631. But it’s been 12 days and the money has not been refunded to my indian bank account. Please take necessary steps to check the detail of wherein my money has been held through the refund process. Thank you, dr. Vineetha
