Worst service ever

My car was towed to Lindsay Saker Midrand on 28 April 2015. On 30 April 2015 Gert Vrey called me and told me it is the steering lock mechanism that is broken, they don't have stock of that specific part but will order it immediately and should receive it by Monday or Tuesday. On Tuesday he called me again, then he told me the part should be there by Thursday. On Thursday I called him, then all of a sudden there were two parts and one of the parts was ordered from Germany, so it will take another week. I'm sure it is going to take more than another week. I don't trust them at all and wished my car was towed somewhere else. I'm also wondering whether it is really necessary two replace both parts on which I was quoted, or if it's just a way to make more money. They gave me the incorrect information, and when I asked if they can give me a courtesy car, the answer was no, which did not surprise me at all, given the poor service I've received so far.
