Power Steering Failed problems of the 2007 Ford Fusion

I brought my Ford Fusion 2007 into tires plus to have a/c repaired. I had thought it was the a/c sensor in the dash, as they are notorious for failing in this make and model. I was right. Despite this, I was not listened to (I'm just a dumb female, right?), and the mechanics replaced the compressor, clutch, and condenser, only to find a/c did not work. In the process, they also moved the motor mounts and the power pump and drained the car of all power steering fluid. I was sent on my way. I was literally unable to leave their lot due to no power steering!! the car also vibrated significantly now at stop lights. I was concerned they damaged the motor mounts as well. The steering has grown significantly stiffer and difficult to turn. Firestone/tires plus agreed to repair the a/c sensor but only if I agreed to have it towed to a Ford dealership in oconomowoc. I was up against the wall, as I was concerned about the power steering issue and safety. It is incredibly scary to have power steering fail when you are driving at 60 mph! the Ford dealership treated me badly (no surprise) and told me "they could find nothing wrong with the power steering. " I brought it to another Ford dealership, under the direction of firestone, and now, I was told that yes, I am correct, the motor mounts needed replacing. They did a brief inspection of power steering as well as a flush, and told me there was "nothing wrong. " when I went to pick up my car from the gordie boucher dealership in janesville, (I was treated poorly here as well), the motor mounts were replaced, fixing the vibration issue caused by firestone/tires plus, but the power steering is even stiffer and just as difficult to turn. Please help. I am being given the run around from firestone as well as Ford. No one wants to step up to the plate. I am concerned about our safety. I don't want my child injured.
