Indigo Airlines — Was not allowed to fly

Address: Chennai, Tamil Nadu, 600001

I was booked on a flight to mumbai, my flight time was 5.20 am i reached airport at 4.30 and i was told seats are full. I wonder after having booked well in advance and being on time how they deny me a seat. I wonder who the hell is the ceo. Imagine a single lady traveller being harassed like this by flight ground staff. This only a way they want to make money.
I had to pay again for the ticket and fly. If there is any courtesy and customer orientation left with this organisation they better change the way the work.

Otherwise balls to indigo & to its promoters.
