To whom it may concern,
My name is nikita bhatia and i recently applied for transcript of marks in delhi university. On october 30th, 2018, i tried to make the payment of fees for the same on their online miscellaneous fee portal through my debit card. But there was some problem, the amount was debited from my account but the transaction was unsuccessful. I tried again and paid the amount successfully through another bank account. But when i rechecked the transaction status for the previous payment, it showed successfull. Now the payment has been made twice. I wrote to the prescribed email ids (Preeti. [protected]@idbi.co.in; neeraj. [protected]@idbi.co.in; bajaj. [protected]@idbi.co.in) on 2nd november, 2018 for refund of the extra payment of the fees, but no answer was received from their side. I am therefore enclosing some information of the same and i hope for the refund of the amount as soon as possible. Thank you.
