Indian Bank — not credited my refund amount

Address:

Anantapur, Andhra Pradesh, 515001

Hello...
I ordered two items in amazon. I made a payment (820 rs/-) for that through debit card. After some time i got a msg that my orders are cancelled n refund will be initiated shortly... And then they initiated the amount to my account. But it doesn't reflect in my account.. How much time it takes to add the refund amount in my account.? Hope u resolve my issue...
