GoAir — non explanatory charges asked while web check in

This is in reference to my pnr l1nw9l for my flight from mumbai to lucknow on 25th feb with the scheduled departure time as 10:35 am.

I tried to web check-in for this particular flight around 8 am on the same day and it showed me to pay around 1800 inr for doing the web check in as a fees towards airport development. Since i wasn’t sure of why should i pay the amount, i was not able to web check-in. I tried reaching out to the call center, but couldn’t get through somehow.
Now, because of heavy traffic, i reached airport around 9:55 am.

I contacted the ground staff and explained my situation, but your team didn’t try to help me instead they told that since i’m late for check-in by 5 minutes, i wouldn’t be allowed to board the flight. Although the gates close 25 minutes prior to the departure time, i was still having 20 minutes to do the check-in. If i had been able to do the web check-in, this problem wouldn’t have arrived. When enquiring about the additional cost while web check-in, they explained it is airport development cost which is asked everytime the passenger tries to web check-in and it is not asked for offline check-in.

My question to your team is that the facility like web check-in are done for customer convenience and not for their additional inconvenience.

Because of this problem, i had to buy a new ticket and my subsequent bookings which were done post my original flight and i paid an additional amount which i wasn’t supposed to. Refer attachment for your reference.
