[Resolved]  Air India — Airline asking to cancel my non refundable ticket due to mistyping in my last name

Address:	700048
Website:	www.airindia.com

On the 26th a evening i booked a ticket from kolkata airport to dhaka bangladesh, by mistake there was a mistype in my spelling of the last name. Now since it is an international flight the spelling of my last name is now different in my ticket & my passport. I than called both makemytrip, where i had booked the tickets both the airline company & makemytrip the only way to amend the last name is to cancel the ticket & book it again. But since the ticket was non refundable so i will be not given any refunds.
I spoke to both asked them i could mail them or go to their respective offices with my original documents & show them the proof. But they are insisting on the same, that would not be able to do so.
Now i'm asking them correct the spelling of the last name. Even air asia does i have enquiried. Now i request you to kindly help me in this regards.
