Hi,

I want to bring into your notice that I booked a railway ticket from kota to Ujjain for 2 people and unfortunately I had to cancel one ticket. It was a sleeper class ticket for 220 Rs. For 17th feb and I cancelled it today which means before 48 hrs . I got the refund of only 100 Rs.
Please clarify my doubts.
