Unhappy with shocking service at BMW auto glen

Not so long ago I was given an attitude by Candice from BMW auto glen. This after I kept on trying to call auto glen over and over again for a booking without an answer. Eventually I decided to drive there to make a booking in-person. I was given an attitude by Candice. She left me attended for a long time. Eventually she told me with an attitude she can book in my car for the following week and I will not be offered any transport to and from work. The morning I dropped off my car I arrived at a time she suggested. She then told me with an attitude that my car is not booked. She then walked away from me after telling me that if I do not listen to her, then she will not listen to me. What ever happened to the days when the customer was right? Only after I demanded service did she then book my car in and organize transport for me to get to and from work. When I eventually got my car back, it was dirty. A courtesy wash was not extended to me.
