Really bad experience

Took car to Bosch Mt Edgecomb and was returned car with missing bolt in steering and main leak that paid to have fixed but they didn't. My steering mechanism could have fallen off and caused a crash. I made a temp did and took it back, after 2 weeks they give me the car back with the leak still there and the temp fix that I made still their. They told me there was no leak and also before I got there that they had the bolt. They mislead me. Cost me a lot of moneyand more problems than when I took it in. No resolution and I don't trust that they are capable of fixing the problems.
