Amazon India — Bug in application

There is a serious bug in amazon application.

Please find the issue i faced,

1. I ordered 7 items and the payment got declined due to you issue
2. Again i did the payment and it succeeded
3. I got a mail that your order is placed with order i'd for all 7 items
4. Suddenly i got a mail that your order failed due to payment declined the next day
5. I called amazon customer care and they said that the payment was declined, i got the order i'd and amount got deducted for all 7 items collectively 3700rs. Don't know how it got rejected for one item alone of 860.

If i have not called them, i wouldn't have got my money reversed. I order lot of items every month, not sure whether something like this happened before.

I request everyone to check their order once thoroughly
