Amazon India — Refund not received for various orders

The refund for the following orders has not been credited to my bank account. When I talked to Amazon customer care they said that it has been processed from their side and it's stuck from bank's end so contact to your bank. But when I contacted to my bank I found out that the amount has not been processed and it has been stuck because of Amazon only. I was expecting this refund on 2th or March but didn't get it. And from there onwards I have been juggling between bank and Amazon.
Please look after this issue and solve it as soon as possible.
