Disappointed Royal customer

I'm so disappointed in my insurance company, was involved in an accident, 2 months ago and the car was delivered on Tuesday, thus past Tuesday. Ever since the car was delivered its ine problem after another. The car doesn't want to start, it starts once in a while, the car gas a steering wheel sign and its difficult to turn vecause the steering is hard. The reverse light lights don't work anymore. I called them and I was that the manager says if it,not their fault then I will have to pay. The point is I was involved in an accident why do they have to concentrate on the body and not the engine. The company they work with the manager came and tried to start the car of which he failed to start it yet they are the ones who fixed the car. They said they have nothing to do with the electrical of the car. As a single woman I'm stuck with a car that starts when it wants to start and the steering is hard.
