Indian Railways — Non refunding of reservation amount(e transaction)

PNR: [protected], [protected]
Recently I booked these tickets for a training program.But I cancelled both tickets. The 1st one, due to non performance of the travel. In case of the 2nd one, I got confirmed ticket in another train on the same day from calicut (Jan satabdi).I received a message about refunding of amount Rs.100/- & Rs.280/- respectively. But I didn't get any refund till this date & time. Hence I demand to take necessary steps for getting my eligible refund.
