GoAir — change of two alphabets in the first name

I have booked a flight for my colleague for 16th of july, 2019 and somehow spelled the name while booking as steven martis instead of stephen martis, the name getting reflected on his identification cards. I called up goair, requesting to allow change of two alphabets from steven to stephen but it was declined on the pretext that as an internal policy go air doe not allow change in the name. So i had to cancel the ticket and book a fresh one. Yes, it was an error on my part for which i had to pay a huge price. Istrongly feel that such internal rules should not be allowed by dgcai because in this way goair must be fleecing so many customers in the name of name change. I have decided to share this all and sundry so that as many people could avoid travelling with goair. What they are doing is a great injustice and getting away with it because indian laws do not take much cognizance of customer rights
