I scheduled service got my car twice through their online reservation system. First time it offered to have the car picked up from my house. Then I a get a call 45 minutes before they are suppose to get the car and say that my service doesn t qualify for that option. I made another appointment for 5:45PM and then I received another phone call saying they cannot do it because there technicians leave at 6 but service is open until 7? Seems like I m trying to hard to get service at this place.
