Indigo Airlines — exploitation by indigo

Address: Lucknow, Uttar Pradesh, 226014

I had booked for a travel scheduled on 10th november 2017, from lucknow to chandigarh, via a connecting flight from new delhi (It was a single booking with a pnr no - chzynk). The carriers were indigo flights 6e-423 (Lko-del, scheduled departure at 10.40 hours, arrival at delhi at 11.55 hours) & 6e-937 (Del-ixc, scheduled departure at 13.50 hours, arrival at chandigarh at 14.45 hours). Reminding the gap of 1 hour and 55 minutes at delhi.

The flight from lko departed 1 hour and 40 minutes late (12.20 instead of 10.40 hours) and because of this my connecting flight to chandigarh was missed. Indigo told me they could not arrange another flight to chandigarh on the same day and i had to travel via road, cab service provided by them.
Now i have few queries.

1. When my flight got delayed by 1 hour and 40 minutes (Whatever is the reason) and i had 1 hour and 55 minutes at delhi to catch the connecting flight, thus leaving me with 15 minutes only to catch the connecting flight, which is humanly impossible considering their rules. Now, what i think they should have done. First option being, they should have informed me the possibility of missing the connecting flight and thus given an option to travel or not. At indigo counter of lucknow airport, i even asked whether i would be able to catch the connecting flight or not to which they gave me a confirmatory answer (That it is their responsibility to arrange the flight). Alternatively, they should have made another arrangement or delayed the connecting flight (As both flights were booked together with a single pnr).

2. On landing at delhi, few persons from indigo were present near the carrier to escort the passengers travelling via connecting flight (Possibly due to the delay). Upon enquiry, the person assigned for escorting passengers to chandigarh replied that my flight had been delayed. But when i asked again (As internet was showing departure at right time), he yelled me in a very rude way ‘whether i know more you’. Not the least, we had a time of 30 minutes to board the flight. He made us roam in the airport bus for 30 minutes without any announcement and finally dropped at the arrival point telling to enquire at the indigo counter, where they informed that the flight had departed at right time.

So if indigo gives us a single pnr for two connecting flights and the first flight is getting delayed, why not to delay the second flight by default. Else provide us a second accomodation the very same day. If that is not possible inform beforehand giving an option not to travel. And after all there is no compensation. Are we paying for such mismanagement by indigo? And why i paid to travel via road. It feels like we are being exploited by this carrier, as there were also several other passengers who faced the same scenario, all travelling via indigo.. It is simply recklessness by indigo.

3. Finally, why should not i be get compensation for the delay in the flight and the missing the flight (Which are completely the faults of indigo)? I did not pay to travel partially via road with all the pollutions. This led to loss of money, energy, time and gave me a lot of psychological pain.
