I was interested in a very specific vehicle and had set up an appointment. I received a call in the morning of the appointment to confirm the at 3pm appointment later that day. I drove up after leaving work early all to find out the vehicle had been sold 2 days before and I had pretty much wasted my time. It would have been nice to have been informed instead of making me leave work early and drive up for nothing. Since I had received 2 calls to confirm. Anyway I was annoyed and considered this to be very unprofessional.
