Poor condition of the car

The vehicle is brand new but it could not start on the second day morning after I got it. Although I called the Budget Roadside assistance but the problem could not be fixed. Finally I found out that the keyless system of the key was failure even I changed the key battery. I went to the Budget shop in the city for help but they did not have same category of vehicle for exchange. I only used the emergency startup to start the engine every time in this 2 weeks.
