Tata Motors — Car start issue

After run of 150 to 200kms if we stop somewhere and then again try to start car without manual push unable to start the car.
This has been happened frequently but not always.
Visited service center they have told that whenever it happens do let us know but this situation happens anywhere where there won't be any people or outskirts only.
Battery status have been checked it it okay and still unable to resolve this issue .
Tried contacting customer care but got very disappointing feedback.
They were pushing it on the name of servicing center when I was insisting them to let me log complain to higher authority but they were completely helpless.
Now the issue I'm facing is happening quite frequently and I'm quite disappointed because of that.kindly provide the solution.
