MakeMyTrip India — airline ticket booking

My flight from hyderabad on ahemdabad was booked for[protected] evening in goair g8 554.

I received a call stating the cancellation of the flight due to operational issues.
As a solution, i was offered an option of a refund or rescheduling the flight book on the same or one day before or after in the airline.

My concern is to leave hyd in the 3rd evening and reach before 10 am on the morning of the 4th.

As evident from the screenshots, there are flights available via the routes hyd - mumbai - ahmedabad on the same tenure.

However, upon the request (Multiple begging as well), i was not even allowed to talk with the senior or floor manager. Let alone the request of rescheduling the flight in the timeframe that was requested.

P. S :
1. I booked the evening flight so that i can leave after completing my work for the day.
2. I have a fractured leg but i am traveling only due to the importance of the meeting. I am going to meet a professor from japan, who is visiting ahemdabad to deliver a lecture in regards to my professional work.
