If you want to talk to me like a human being, I'll bend over backwards to help. If you want to call up and take out your frustrations and treat me like dirt, you will get nowhere.
The customer isn't always right. Too many people have it in there head that they can make outrageous demands and treat you like dirt in the process. I reserve the right to refuse any customer. My time is better spent dealing with someone who is a worthwhile realistic customer.
On the other side of the coin, if I find myself dealing with a company that doesn't seem to care, I won't challenge them, or argue. I'll just take my business elsewhere. If I experienced problems with 2 dealerships, and felt it was their fault, I would simply sell the car and take my business to a company that appreciates it.
