I got a similar response when I called. My pre order number is 9336. I have seen multiple pre order numbers well higher than mine from others assigned to the announced dealers that told them theirs was in production, or already produced and on the way, scheduled to be delivered end of Nov., early December. Ineos did not corroborate that info, and seemed to imply it was incorrect.
I queried this last week and was told that they are finalizing the process. If you request a dealer change then INEOS will contact you directly and help you to do so.
