Indigo Airlines — Inhuman behaviour by Indigo staff

Address: New Delhi, Delhi, 560075

I went to drop my mother Mrs. Shalini Chinchwadkar, 80 years old and wheel chair bound for Bangalore - Nagpur flight Indigo light on 12/Jan/2017.
We reached the airport at 5.15 for the flight on 6.05 but have to wait for wheelchair for few minutes.
When she went inside on wheelchair, she was denied entry in the airplane on the ground of late reporting.
We both requested the ground staff to please allow her on the flight looking at age and physical condition.
But the staff on the external counter was ruthless and rude and simply denied to help.
There was sufficient time to board her, but nobody came to help.
I had to transport her back to home, which is very difficult for her and book another ticket by paying additional Rs. 3800.
This inhuman approach of Indigo staff surprised me and our family and we went though a very bad day.
I know there are some rules and we should try to follow them. but at the same time, we should have some empathy for elderly, differently able and children, which Indigo has failed to showcase.
