Worse Service ever !!!

My van has a starting, because I was near the dealership decided to visit them about it. Had to leave my car behind last week Monday so they may fix it on Tuesday. When I followed up late Tuesday the car was not ready and no one bothered to notify me. Same thing happened on Wednesday, was further given an unapologetic statement by their staff member. Which got me very angry. Thursday then she says my car needs authorisation for service as it has passed the required milage. I agreed to that. To this Monday I have not heard from Ford what so ever. I guess it takes centuries to service a car at Ford. Have never seen such poor service in my life. This is totally crazy. In a whole week, I have only received one call on an update of my car. Contacting their Head office is a waste of time also.
