Very poor service

Very poor service, Booked my vehicle for a service, the dealer confirmed that the vehicle was booked for it's 10000Km service, I arrived to book my vehicle in just to be told that they cannot help me on that day and I need to rebook. Why do you make an appointment?????? Tried to speak to the service manager but he is to busy to speak to me. Absolutely atrocious service, don't know why a person would want to deal with such incompetence. Will go to Pat Hinde at least they know how to deal with their customers
