I booked one 1AC Tkt for my wife from YPR to DEE with confirmed status for INR 4320/- in YPR-DEE Duronto. Later, I too decided to join and got this ticket cancelled and booked two 1AC Tkts for INR 8620/-. Now, when I checked my account, out of INR 4320/-, I got a refund of just INR 4230/ for cancelled ticket. I thought it should be just a deduction of INR 20/- only. Can some tell me why this additional INR 70/- is deducted..........
