Indigo Agencies Private Limited - Flight cancelled and delayed by 3 hrs. but no food arrangement done

I and my husband booked ticket for **.** Indigo, Chennai to Maduai on **th Sep. ****. This was cancelled and we were asked to wait for another flight at a particular place. Being lunch time and my husband being sugar patient, we suffered for want of timely food. Although we have been assured food, We were given boarding pass for another flight at *.** (flight no. *E ****) and no food was given either during waiting time or during flight time. Due to starvation, we, especially my husband suffered and was to refer doctors treatment. This caused not only mental stress but also affected our normal health. The airline is solely responsible for this noncourteous attitude of the Airlines management.
