Indigo Airlines — Wrong information mentioned on the air ticket

Address:

Mumbai City, Maharashtra, 400027

Hie,
On 4th Feb I was flying to Chandigarh from Mumbai, flight timing was 9.50 so according to that we left from home. As on the ticket it was mentioned to board the flight from CHHATRAPATI SHIVAJI INTERNATIONAL, so we reached there. After reaching international airport it was informed that flight is to be board from domestic airport. Due to lack of time it was very difficult for me to reach domestic airport in that short span of time as there is always traffic an issue in Mumbai. as we are not so frequent travellers so not aware of all such. Kindly request you to please mention the exact detailed information of airport and terminal from where the passenger have to board the flight. Many of the passengers must be facing such an issue. Please rectify.
