Airlines and Easemytrip not correcting spelling mistake

I had booked 3 tickets to Bangkok via the easemytrip website. My travelling date is 24th October. My ticket booking id is EMTxxxxxxxx1. While booking, unfortunately, I entered an incorrect spouse name. Please help me in correcting this. I have dropped multiple emails and cald them on their customer care to correct it. but no luck. Airline team says travel agent has to change and easemytrip says airline needs to change. but no one updating name in air ticket.
