Un Friendly rules of Air Lines. Review on Jet Airways

My Daughter’s marriage fixed in March-2017 at Delhi so I booked 25 tickets with Jet Airways for my guest from Mumbai. Unfortunately in one ticket name of my guest was given her median name(before marriage name) but present name after marriage is different. So I send several mails to Jet airways for changes & ready to pay reasonable correction charges. It’s my surprise, I have been informed that there is no way to change name & I lost all 100% amount paid of ticket! I must buy new ticket again. That mean for same person & same booking I have to pay two times to Airline! This un-friendly rule must be stop. Charge correction fees but 100% fare amt. should not be lost. How many poor people will suffer as for such mistake? Our respected P.M.Mr. Modiji every time talk about many benefits to citizen of India & here Airlines are penalizing their guest for some mistake as like Airlines never making any mistakes? You all please take care or Airlines as like Jet airways are waiting you to grab your hard earn money.
