Mechanical Jack problems of the 2000 Honda CR-V

Problem began when vehicle was purchased, the jack that was provided was not stable. Just a slight movement will cause the jack to fall down to the ground. Last weekend,the tire went flat. When the car was jacked up it fell down. After this, there was a mechanic across the street who was able to lift it with a floor jack which caused misallignment of the vehicle. Once while jacking up vehicle it fell down on the owner. The right hand and right knee were injured , and had to have cortisone shots. There was a vehicle repair cost caused by the floor jack, there was about $475 in damage to vehicle. Owner has not contacted Honda.
