Spice Jet Airlines — frequent change in flight timing

Address:

Hyderabad, Andhra Pradesh, 500032

I am travelling in flight sg 708 on jan24, 2019. Scheduled timing for the flight has been changed thrice till now. Initially they preponed the flight to 2.45pm on dec 3, 2018. Then they preponed it again to 2.30pm on jan 23, 2019 late in the evening at 9.30pm. And, finally they rescheduled it again at last moment (At 12.46pm on jan 24, 2018) to 3.15pm.
My concern is that too many reschedules will give a doubt whether everything is good with airplane or not. Moreover, customers may have their own plan based on flight timings and so many reschedules will surely disturb their scheduled plan.
