poor and bad service I got at the Glen Auto BMW

Hi my name katlego <br> <br> I am reporting a bad/poor service of my car that happened at The Glen BMW AUTO. When I brought the car for Service and now nothing is working. They even gave me the car without testing it . When I driving nothing is working all the controllers.<br> <br> I am not happy with their services and thing the world should know how BMW is treating us and also taking an advantage.<br> <br> I am so angry right now.
