Indigo Airline - Indigo airline: Reached on time but marked as no show.

Flight departure time:**:**,Total fare:INR **,***.**

*)I have entered terminal by **:**, and reached on counter no ** by **:**. from there I was sent for baggage scanning.I understand that scanning is important but as my check in closes at **:**,why priority was not given to me?
*)I requested agent on counter no.** at Chennai domestic airport to allow me as I have emergency(my grand mother is expired and I have to go).They were rude enough not to allow.
*)I was said by agent on counter no.** that all seats are full on flight. I have a valid ticket and I am not yet boarded,how can all seats be full?Do you sell tickets at higher price due to Festive season?
*)I was said by agent on counter no.** to check for next flight available on same day, when asked for any extra charges,they said it would be managed on same ticket price. When checked on Indigo customer care counter, they said we do not have seats on any flight today and if booked I need to pay INR ***** .Why wrong information is passed by agent on counter no.**?
*)When I asked agent at counter no.** to call their supervisor,answer was not possible.why?
*)when called customer care(Mr.Mehboob)) , they said refund amount will be INR:*** and I am marked as no show.So refund is as per no show policy.Its conflicting as wehn I asked customer care on airport it was said that refund amount will br INR ****.
*)I asked agent in customer centre at aiport for cancellation of ticket which they said, I have to do online.Also been said"you can walk and cancel as internet is there in every smart phone now".As if it has been hilarious.why such pathetic customer handling?

Please address that as soon as possible.
