MakeMyTrip India — fake promises for my date changes and running away

Address:

Anand, Gujarat, 388306

I have booked a ticked on 7th of november this month and after booking my ticket, i wanted to make the chamges in it. I called customer care of mmt and they took a request but they did not resolve the issue since it is 23rd of november today. Whenever i am trying to call on their customer care, they are just saying that their concern team is working on it and they need addtional 24 or 48 hours but after 48 hours it was the same situation.
All are the players and they runaway after making fake promises.
I have recorded their some of calls where they promised and runaway.
