Is it legal for my mechanic to do this to me?

I brought my car in to be fixed because it was making a funny noise. I was told it needed a new power steering pump. 1200.00 later, it still wasn't fixed, so I brought it back. They said they needed to replace the rack and pinion steering. Another 1280.00. Picked it up, still making noise. Brought it back. They called me the next day and said it was an air bubble. Picked it up, not fixed. Brought it back and they replaced the power steering fluid reservoir, saying it was warped. Tried to make me feel like they were doing me a favor because they didn't charge me for it. Drove away, still not fixed. After getting home and examining my receipt, noticed the reservoir wasn't mentioned on there. Stopped by this morning to ask if they could print up a receipt for me that included the reservoir so that i could keep it with my maintenance records. They said they couldn't do that because it was only written in the mechanics notes on their computer. Even after my urging them to do it, they refused. As you can probably understand, I do not want to go back to this place. Is there anything i can do? Can I get my m oney back and/or have them pay for me to get it fixed right somewhere else. I can't afford to pay someone else to go through all of this again. Any suggestions?
