Brakes question

[n00b on demand]

Well this has been a terrible experience. I ended up getting real mad and yelling at them. They took 5 hours to take it apart and clean it and readjust them. I take it home and its coming from the rear left . The mechanic said whatever you hear its coming from the front....i said it doesnt take a genious to hear where the noise is coming from. They said there is nothing more they can do because they did everything and they said they can't find anything wrong. So i said maybe you just gave me ****ty parts you bastards.....then they offered to get me dealer parts and credit me for parts i bought and i would just have to pay the difference. I said no thanks and walked away....i dont want them touching my car.
