Indigo Airlines — unprofessional and rude behaviour of, indigo staff not cooperating with the passengers at all

Address: Varanasi, Uttar Pradesh, 211008

On 4th august i had a flight 6e-6913 from varanasi to hyderabad at 6:50 pm. I reached at 6:15pm and requested them a lot to allow me to catch the flight which was standing at the runway. Though the indigo airlines says that the check-in closes 30 minutes before departure but they did not allow me. I only had hand baggage but still the staff was rude to not allow me. Instead i checked later the flight took off before scheduled time around 6:39 pm. How could they not care about a passenger just to reach the flight on time. Its so selfish and unethical. Just to maintain their reputation they can cause trouble to their customer who has paid so much for flight booking thinking that no one will get to know about this
