[Resolved]  Indigo Airlines — harassment for aged people

My parents (Amit bhattacharya/sutapa bhattacharya) were supposed to travel via 6e 822 from kolkata to bangalore. I am totally aware of the policy that you hold regarding timely departure. However, my parents are old and my mother being on high medication due to ailment had to go to the washroom.
My father was at the gate asking to wait for a minute, am sure this would not have delayed the flight in any case. We are educated people, do realize the importance of time. But, manuel was the indigo staff at the gate who refused to accept my father's presence at the gate. I believe you are not the only airlines running, if you cannot care and respect elderly people, you do not deserve to run any service. Now, the flight needs to be rescheduled, my parents are waiting but now they say there isn't any provision to confirm soon. When my parents were travelling last time to bangalore when i met with an accident, your flight was delayed for 3 hours, if that was justified i am sure one minute late for a genuine cause can be incorporated.
I am even aware of the flight departure procedure, it does take another 10 15 minutes post boarding to departure, so i am sure my parents could have been incorporated.
Keeping this in mind, i would like immediate help and assistance for my old parents at the airport and a confirmed accommodation in the next flight. If not kindly make your tag lines clear "indigo is not fit for aged people".
