Airasia — Flight tickets

The issue that I have experienced was: Regarding PNR G9IRFE

I had booked 2 flight tickets from Delhi to Bhubaneswar on Air Asia morning flight at 7:40 AM from Delhi and it's arrival time was 9:20 AM at Bhubaneswar. The total cost for booking the flight tickets was Rs. 4708 for 2 tickets. But now air Asia had sent a mail that, they had cancelled the scheduled flight and rescheduled my confirmed booked tickets in another flight which
is a connecting flight via Pune which leaves Delhi at 8:50 AM and reaches Bhubaneswar on same day at 2:00 PM. But, I want to reach Bhubaneswar before 10:30 AM; as I have unavoidable commitments in Bhubaneswar. Now as my booked flight has been cancelled and rescheduled, I want to book tickets on different airlines. But the prices now have increased and
there is a huge difference in the ticket fare.

I request Air Asia to provide the difference in the air fare for Travelling form Delhi to Bhubaneswar on 16.09.2021. During booking the flight charge was Rs. 4700 and now for a new booking it is Rs. 13000 ( August 26).
When i was booking the tickets, so many other airlines were providing tickets for the same fare, that is approximately 4700/-. But by my mistake and misfortune, i chose Air Asia. Now the flight is canceled, and you are saying I will get the "Full refund", that is 4700 Rupees; for that amount I will get train tickets only.

It occurred on: 26/08/2021

Now, the airlines company, that is AirAsia canceled our tickets without our concern. It is complete cheating.
