Spice Jet Airlines — Non-operating A.C. during the flight

Address:	Ahmedabad, Gujarat
Website:	spicejet

I traveled on sg636 from ahmedabad to mumbai on june 5th 2017, departure at 5:40 a. M. On boarding the flight i had reported cabin crew about very warm temperature in cabin. She responded that "once flight will take off, ac will work perfectly". Again after take-off i had called upon ms. Astha and asked her as to why ac is still not working... And same reply was given. Half the way, it was announced that airlines regrets for warm temperature in cabin.

If it's known that ac is not working, than why the flight was allowed to take off or it's a compromise by maintenance department? It was about 80 minutes in oven.
