Hello!!!

You can provide the screenshot as the proof if you have of the transaction that you made . If that is not available then you must go the bank from where you made the payment, there's a machine where you put in your passbook and last transactions get printed in it . You can produce the photocopy of it . Or you can also visit your online website of your bank and log in with your net banking id and password. There you will get an option for transaction history. And you can screenshot it and get it printed.
