i have paid for NPTEL but it's showing that the payment has been failed though amount has been debited
How to get a refund on NPTEL?
Once the exam fee is paid, arrangements will be made for you to take the exam. You may choose to cancel the exam registration before the prescribed deadlines mentioned in the Timelines sheet available in our portal. If exam cancellation is done before the deadlines, exam fee will be refunded within 2 to 3 weeks.
