As I understand it, it's not that they "lost" his order exactly, but that it was modified for someone else in another state by the same last name thinking they were working on his order. Probably someone called in checking on things and someone pulled up the wrong order and changed it, maybe there was a color change or such to the other guys order and someone wasn't paying close attention and grabbed the wrong account. At least that's how I could see this happening. Huge mistake by some DA if that's what happened and sure it also bears looking into who that other person was in Florida and how this could have happened.
My order was end of June and we got our car after the 3rd scheduled attempt on 9/23. Just a few weeks ago. It's possible that Tesla hasn't gotten to orders placed at end of July yet and the delivery would not have necessarily happened yet. But I have no idea how they are doing this so again just a guess. And clearly we've seen exceptions all over the place. I do think the OP should be given his place back in line based on his order date and the car sold to him for what the order confirmation was for.
BTW regarding Tesla being sued by the State of Nevada. That amount was paid, but it was in part as I understand from the press because Tesla acquired Solar City and was questioning how they were calculating what Tesla owed for a worker's comp insurance contribution due to the acquisition. I think that's understandable trying to fight or negotiate something like that. Once you pay it if you are disputing something, much harder trying to get any amount back you might be due. I use to have to prepare and file the unemployment comp forms for a small company and when people are fired or laid off the company gets wacked quite a bit of money as the their contribution rate goes up for quite a number of reporting quarters. I can see why Tesla would not want to be penalized for rates set for Solar City. Sure the lawsuit was Nevada's way of leveraging Tesla with bad publicity, making it seem maybe like Tesla didn't have the money to pay the contribution and playing into short sellers rumors. Sure did get a lot of negative headline press don't you think. Guess it worked.
