Dear Nilhil, After successful payment, candidates will be able to print the Confirmation Page. In case the Confirmation Page is not generated after payment of fee then the transaction is cancelled and the amount will be refunded to the candidate's account. But CMAT hasn't mentioned any time frame for the refund of the amount. If you have made 2 payments and once was deducted from your Ac but not credited to the application, it will be refunded. I would suggest you to keep an eye on your Account from which the unsuccesful payment was made.
