Spice Jet Airlines — flight delay

Dated:[protected]
Flight no: sg6362, pnr no: idrmfn

I booked a direct flight from coimbatore to delhi (Sg8526) (Direct flight). It got canceled and got a prior information regarding it and rescheduled to connecting flight as stating there are no direct flights running between these places. The rescheduled flight is scheduled to depart at 12 pm, but it got delayed 3-4 times and finally departed at 5 pm. Actual connecting flight scheduled at 05:15 pm but due to delay in the actual flight, the connecting was changed to another and it was scheduled at 09:55 pm. The flight departed at the prescribed time and reached delhi at 27/04/2019 12:30 am.

Issues:
Total no. Of passengers booked tickets are 7, out of which 5 are physically unfit and aged too. The sole reason behind booking flight is fast (03 hours) and easy journey as many people are unfit (Because it will take a day on the train). But the direct flight got canceled and got to reschedule to connecting flight because the return journey tickets are already booked. Even it was a connecting flight the actual traveling time is 04 hours (Approximately). Thought 4hrs was no time and we can adjust, so booked the seats for both the flights by paying the additional charges.
Firstly, the actual flight was delayed by 5 hours after issuing the boarding pass.in between which no services were provided (Refreshments and exact info. Regarding flight). Its basic rule to provide refreshments if the flight got delayed by 5 hours. As many of them are physically unfit already they are almost exhausted by the time they boarded the actual flight.
Secondly, the connecting flight from mumbai was scheduled to depart from a different terminal on which the actual flight arrived. Its the responsibility of the airline management to shift the cargo between the terminals as we booked the connecting flights together. And they not even provided facilities for the transportation of passengers. As the connecting flight time was ticking, we are in a hurry to reach the other terminal to take the boarding pass of the connecting flight. As none o[censored]s are fluent in the local language of mumbai, faced severe problems during transportation (Traffic). And the time gap between the arrival of actual flight and departure of the connecting flight is very low, we are pushed to rush despite exhausted. As we are already exhausted waiting for the actual flight (05 hours), these hindrances made us almost sick.
Finally, even the connecting flight was delayed by 20mins. And then we finally departed around 10:20 pm and reached delhi by 12:30 am the next day.

*expected travel time for the flight we booked first 03:00 hours, actual time it got 12:00 hours (+2 hours, as we reached two hours before to collect boarding pass for the 12 pm flight).

*no assistance was provided between this time.

*no refreshments were provided.

*no cargo shifting and travel assistance were provided for the connecting flight.

Because of the delay and the lack of proper hospitality by the airlines made most o[censored]s sick throughout the journey, which resulted in devastating experience in our trip (One of the days we are almost spent our day in the hospital).
So that our trip ended on a bizarre note.

Tried complaining through spicejet customer care but there are unable to reach.

So, we urge for the refund of the additional expenses we incurred during the journey and the connecting flight and the compensation for the problems undergone.

Thanks.
