Terrible Customer Service Received

As a first time car owner I would expect to have all the information regarding services and/or repairs explained to me. Upon telephonically booking my car into Ford Woodmead I wasn't informed about my car exceeding its annual service period. Only once my car was received at Fury Woodmead only then was I informed about my service being \out of date". Now I don't expect the dealership to be held fully responsible for this lack of customer service"
