SPICE JET AIR LINES - Missing of connecting flight due delay in initial flight

On **.**.** we (a family of *) had a flight booking from Kolkata to Dharamsala on spice jet airlines. The initial flight(SG****) was on *.** from Kolkata which would reach Delhi on *.** and the next connecting flight from Delhi to Dharamsala (SG****) was on **.**. Initially we had received an intimation that the flight from Delhi to Dharamsala is pre poned from **.** to **.**. When we reached the airport we received a message that the flight is delayed and new schedule is from *.** from Kolkata which would reach Delhi on **.**. We immediately contacted the spice jet counter staffs regarding this and they assured that spice jet staffs of Delhi airport will help us to board the connecting flight. We again received an intimation that the connecting flight from Delhi to Dharamsala has been rescheduled from **.**.** to **.**.** timing is from *.** to *.** which is again changed the new timing being *.** to *.**. The personnel at the counter accordingly issued us boarding pass and told that no accommodation will be provided by spice jet for this situation. I am traveling with a *.* year old kid and I am really surprised that without any prior intimation the flight timings are changing so many times and nobody is bothered about the convenience of the customer and no care was provided by any staff of the company. Neither any accommodation was offered by them. We could not catch the connecting flight due to delay of the initial flight but no responsibility is shown by the airlines company towards it.
