Nexa — Detected car

From the day I have purchased this maruti Suzuki ciaz from nexa dilshad garden i am getting continues problems in the car and this is totally disappointing because after a lot of complaints no issue is being resolving.
we can go any where in the car but if we park it once for 3-4 hrs we are not sure that it is getting started again or not as this is the 3rd time my car has been not starting on mid road with out any reason. even after replacing my cars battery last month same issue is facing and within 3 years of purchase my cars battery brokedown?
I want a genuine action right now on this car as this is very shameful for company like suzuki producing service in this manner. if the concerned action are not getting I will be throwing away this car in auction below market value prices
and suzuki connect app also not works
