Power Steering Fluid problems of the 2005 Chevrolet Malibu

I took my car in on 9/3/15 for a recall on power steering torque sensor assembly, a brake component, and gear shift cable. My car had the issue of loosing power steering prior to me bringing it in on one occasion. After getting my car serviced at chuck hutton chevy in memphis, TN for the recalls only one week later my car began making whining, grinding noises every time I turned the wheel. I first thought the car needed power steering fluid, however I was advised that since my car had an eps I couldn't put power steering fluid in the vehicle. I decided to take the car back to chuck hutton because I was not told when they did the repairs that anything else was wrong with my car. I assumed perhaps a mistake was made and a bolt was not put on properly. When I took the car back I was told that the car needed a power steering rack, new tires, and wheel alignment. My tires on my car are barely 6 months old and you can now see the thread and prior to taking my car to get the recalls done on it I had my car fully serviced in August. I feel that my car was tampered with. The servicing agent told me my car was leaking power steering fluid and the ps rack was badly worn down. But my car has an electric pump and their is no fluid to leak as the supervisor told me when I came to him to resolve my concerns. Yes, I tried to resolve the issue with the supervisor but was brushed off and told my car was old. As baldly as my car sounds I feel that if it was really wear and tear they would have seen it when they looked at my car the first time and notified me. I wasn't notified leaving me to believe my car was tampered with so that I would have to bring it back for expensive repairs. If not then what needs to be fixed could have caused an accident and killed me or my children because they didn't notify me there was a problem when I took it to them. Either they are negligent or crooked.
