Cheapticket.in / Airtickets India — change of name and reissue of ticket

I requested middle name of passenger to be added to name in ticket i had booked just an hour earlier. Cheaptickets.in got back saying i would have to pay cancellation charge of rs 16000 while airline says they can reissue ticket with new name for just about rs. 2700 but i had to do through travel agent whom i had booked ticket. Seems like a total scam this website - rs. 16000 just to cancel a ticket i hadn't booked an hour earlier
