IRCTC Online — ticket not confirmed but amount debited

Address:

Chennai, Tamil Nadu, 600117

I ve booked 4 tickets from. Chennai egmore to tirunelveli by kanyakumari express on 08.10.2018. Out of the 4 tickets two were availed with senior citizens concession. After payment through my icici bank a/c i got a msg like 2 lower berth criteria not met. Amount of rs.1252 got debited from my a/c and ticket not confirmed. So i should get it refunded, so that i can book confirmed ticket again. I would like to get a reply. Thank you
