Bad service and Car damage

On the 26 March 2015 I took my car BMW 320i for a service in Ormonde Car service City. The service took the whole day and I was called to collect it but I soon realised that the brake light was not clearing even when the handbrake was put down I took the car back and was told that they need to reset the car. <br> week later the car started to smoke so much it was embarrassing . Just after a few days the car started to liking oil. I took the car back and the Guy that was helping me Ofentse said that they did not do the engine flush as \some"of the cars don't need that. He said I should leave the car so that they can check"
