Bad service

I had the worst service at Bosch in Benoni better called ADE. I took my car in to get the injectors fixed but my car stood there for 2weeks un-attenend. Then when I called them, they told me my starter motor needs fixing. Thier quote for starter was too high and they told me I must come fetch the starter and fix it else where for less. When I did that then they tell me I must come fetch my car and fix it elsewhere. The initial reason my I took my car there was never attended too. Can you imagine 2 weeks for nothing!
