Update: received a phone call from ANOTHER person in Las Vegas (By far the most accommodating, yet!) Monday. Car was in Atlanta area center, and setup home delivery for Thursday morning (425 miles away). Had check FedExed, from Credit Union, and received by Delivery Center in Atlanta on Tuesday morning.
6:00 this evening, the day my car is set to arrive here, and I check my Tesla account page. The delivery schedule was changed to five days later. No phone call. No Email. Nothing.
I called the accommodating person in Las Vegas,who I assume is in sales, immediately. She looked on the computer, noticed the change in time, and had no explanation for it. She said she couldn't imagine why there was a change. She attempted to message my Delivery Advisor (Wait... I HAVE a delivery Advisor? Who is this person?), or anyone else at the Atlanta center, to no avail. Now... I know it was 4:30 Las Vegas Time, 6:30 my time, and 7:30 Atlanta time. So, they had probably left for the day.
She also told me she was able to pull up the calendar they use, and was able to change it back to the original time of tomorrow morning at 10:00. I asked this Las Vegas representative if there still a way they will get a car to me, 425 miles away, after reverting the calendar at this time? She assured me that yes.
My pessimism is increasing, as well as my disappointment in this process. The updates will continue, until the car is received, and the smile returns for the anticipated product.
