I had paid the fees from e chalan but didnt got an confirmatory mail instead its showing invalid reference number so what to do
Dear Vasant, if you haven't received a confirmation mail, chances are high that the payment didn't go through. Please check with the bank if the payment was processed. Candidates have been facing issues with E challan payments. I would suggest you to try making payment through alternate modes like NetBanking or through Debit Card or Credit Card. Only a confirmation page is a proof of a successful payment.
