Indigo and Physics department have fucked me🙏🏻

FY student, booked flight tickets for 19thevening (last day of sem given in the calendar), and these guys kept Physics Lab CIE on 19th, no problem, ill give and then leave Indigo being fucking retards decided to cancel my flight tickets today and shift us to a flight on 18th, and if I cancel this flight ill have to book a new one which is 20k+ due to the ongoing mess at Indigo I called and asked the HOD very respectfully if something can be done such that I dont bear a loss in both marks and money, if they wanted to they can shift me to a date before 19t(which is done for a lot of chem cycle students for ticketing reasons itself), but they said no, I dont blame them fully but why do it for chem cycle students? The whole scenario was not in my hand and now i face consequences ggs
