Garden city motors Bloemfontein very bad experience

I've been to garden city motors Bloemfontein for a recall on my mercedes-benz airbags. After receiving my vehicle back I noticed that the air ven shifter was broken. ( THEY DID NOT INFORM ME OF IT) after getting home I saw they removed rubber from my engine and Ive also not been informed of such actions. They overcharge clients and are hostile.
