I tried to book ticket on 10th october, 2017 for train number 12029 from new delhi to beas. During booking time, on payment page i entered the all credentials and press ok, after two seconds it shows me error. Money is debited from my account but ticket is not booked.
I waited for 5 days to get my money back, but i still not get my refund back.

I need my money back please do the needful.

Thanks.
