Spice Jet Airlines — Flight delayed

I want to High the rediculus flight service of spice jet. I have booked my ticket from Mumbai to kanpur on 10th Sept at 11 am.
1. They rescheduled the flight and did it via connecting flight via delhi. No prior info on call was given. So now the rescheduled flight are 10th sept 00:35 and then it will reach Delhi at 3am and then 7 hrs layover in Delhi and then again 10 am from Delhi to kanpur. So this was the sechedule now.
2. We reached the airport and now the staff is saying that flight will come at 3 am. Passenger waited and at 3 am the staff was saying that it will come at 8 am. Like what sort of service is this. No prior info no arrangment nothing and above that the staff is behaving so pathetically to passenger.
3. Flight came at around 8am and then reached Delhi at 10 am and becz of this passenger missed there connecting flight.

Such a unacceptable service and rude behaviour of staff.

We want full refund plus penalty on this so such a bad service provided by spice jet.
