Air India — Booking process incomplete

Address:

Ernakulam, Kerala, 682004

I tried to book an air india flight from kochi to bangalore for 01 mar 16 online. After i had entered my account info and otp and processed the payment the amount was debited from my account but the web page showed 'something wrong.Pls try later'. Neither did i receive any messages or email saying about the confirmation of my flight ticket. It was very important for me to be on that flight. I tried to bring up the point at the airport too but the officials were equally less helpful. Money is not the problem but trust is. I hope necessary actions will be taken as soon as possible.
Flight details i had booked were as follows.
