Power Steering Pump problems of the 2005 Ford Crown Victoria

Steering started feeling stiff while on a long road trip when I went to change lanes. When I returned home I parked it for a month. Had a few people look at it and they found nothing wrong. Drove it on another long trip and it slowly became worse. Felt like the car was floating opposite my steer or delaying the direction I would steer. Felt like it was catching on something or being block from movement. Had it looked at again fluids check ,rac checked,pump check,greased up. Let it sit again for sometime then took it down the street and steering would not turn. Had no control almost caused a serious accident it took bruet force to save us. Had it looked at again and he said the steering rod looks strange in movement nothing he has ever seen before and that the arm it self looks bent. I now have a car I can not drive and no one can fix becuase they don't know what to fix. I can't even sell it knowing someone could die.
