I've a very grave problem which might be silly because of the lack of my knowledge. I've booked 4 pax from DLI to BUI online from IRCTC. Now, I want to cancel just 2 pax from this e-ticket. Found no option on IRCTC booked history and cancelled history. And the clause in this is that the E-ticket was booked on my brother's credit card who is in Singapore right now. Please guide. These are AC tickets and iam loosing money on it. HELP.
