Always Delay Indigo Airlines. Review on Indigo Airlines

Expensive price comparing to other.I have traveled from kolkata to Delhi last week to attend my friend marriage anniversary.First I was told that the flight is delayed for 2 hour.I received another message from Indigo informing that flight is delayed for another 30 minutes.Once I have board on flight the Air-hostess has not greeted properly. In the flight the flight attendant were not even worrying about the customer.I pressed the button to call someone for a glass of water 4-5 time.But no one came even once.very worst and horrible service from Indigo due to all this.The seating space is very small I couldn't able to seat not even sleep properly due to small seating space.I had bad experience with Indigo Airlines I am very upset.I advice to every one select other Airline rather than this.Horrible service by Indigo airlines.
