Bad service experience

Had an extremely bad experience at this dealership with my service. My vehicle was given back with a cracked front windscreen. Even though the service manager knew about it my car was delivered without informing me. I had to discover the crack as i was leaving the dealership. Upon going back to find out more about how the crack happened, there was a total unwillingness take ownership for the crack and blame was just passed onto me. I found the response to my questions completely lacking, upon trying to find out why i was not informed about the crack upon taking delivery of the vehicle i was told by the service manager she had a very busy day.
