Ola Cabs — About the ride I took and unprofessional behaviour of the driver

I boarded the cab with my mom and in between the trip we were asked to get down from the cab due to battery problem in the vehicle, also he has charged for the trip . This is unfair as we were asked to get down without an alternative . How safe are your cabs to travel with such unprofessional drivers ?
How can we board cabs with a trust of reaching home safely.
I need proper action to be taken against the driver along with the refund .
