[Resolved]  HDFC Bank — Refund for online purchase not reflected in statement

Made an online purchase (via Amazon) but had to cancel later. Amazon has initiated and completed refunds from their end and even received text message from HDFC saying that 'refund has been carried out and money has been credited back to account linked to debit card'. However on balance inquiry and on checking statement and balance online, the refund/credit transaction is not displayed. Why is the refund not showing up or being reflected in my bank statement despite confirmation message from the bank itself? I'm really worried.
