I have appointment with a saleman this Sunday with a confirmation with the director to test drive two cars. I have confirmed on Saturday that I would come, but when I showed up to the dealer, they told me both cars were sold, and the saleman confirmed to see me was gone and not at the dealer. If the cars were sold, at least let me know so I didn t have to drive almost 2 hours back and forth. What s the point of making appointment and then you didn t keep the appointment with your customers. So disrespectful and unprofessional!
