Make an appointment for service to only have my car taken in over an hour later, for just an oil change. And then am told the car is ready for pick up 70minutes later! Awful service, every time I go there with an appointment time I need to make sure I have my whole day booked off because the shortest time I've had to wait there was 3.5 hours.
Unnaceptable, and some of the staff members are quite rude as well.
Will not be going back.
