Hi, guys just need a help. I had booked a ticket in this train for 4 passengers in SL class from LD to MRJ via IRCTC App. Total Amount charged was Rs. 580 but i had to cancel it so did it same on the app but surprisingly the amount deducted was Rs. 480 and only an amount of Rs. 80 is refunded back. Will my remaining amount after deducting cancellation charges be refunded back or this is an error on part of IRCTC ?
