Their field team made an appointment for Friday at 9 AM. We had discussed my availability and the appointment was predicated on the fact that I had to be in Oak Ridge that afternoon. I then received an email the next afternoon that listed the appointment for 5 PM that Friday. I communicated the problems with the new appointment and the fact that the field team had set the appointment. I was flatly told "take it or leave it, we really don't care about your problems".
