Indigo Airlines — Rude behaviour - Wants to make money

Address:

Hyderabad, Andhra Pradesh

On 29th Nov, 6 o[censored]s reported at 9.35 for 10.00 am flight in Hyderabad to CHennai. We were not allowed to board the flight, the behaviour of manager at the counter Mr.Shamit (not sure), was rude. I think they gave the seats to other people. His Manager Mr.Rajkumar was polite but could not help us. They asked us to pay 43K more for the evening flight. When posted in twitter, we got the call. When we gave the PNR No., they could not trace our tickets. They promised to return the call in 30 minutes, without any additional charges, but not received the call till today. Reference -
