Indigo Airlines — Flight reschedule and handling

Dec 22, my flight was at 12 Pm which was completely gone. Then I got put on a flight at 3.10 pm, and was told I can wait in the lounge which I found charges Rs 2400 + tax!! what kind of a joke is this. I am an NRI with a foreign passport and I had a corporate ticket which in your domestic flights is the highest fare, yet I was not given a seat on the next available flight. I would have expected compensation and at the very least complimentary lounge. I purchased Rs 40, 000 worth of Indigo tickets this month, which I will never do again, and surely will no recommend this airline to anyone. And given teh amount of contacts I have, surely Indigo will rethink their customer service!
