Bank Of Baroda — refund sent but not received from amazon

I requested an refund at amazon for a product of rs 499 on 19th january and they refunded it on 21st january but it never credited to my account. Amazon gave me the refund reference number but bank said that the amount was never received. So i need to file a "charge dispute" on them, to get the full details. I need bank to resolve this issue as soon as possible or i'm gonna take some legal action.
