I was in the same situation as you are. I ordered 2/27 and by May, most everyone at least had production numbers and many had cars in the production process. Sales person kept saying "still waiting for information". I emailed him about once a month and that's all i ever heard.
In May i had discovered the Resolute edition, so i asked if i could change my order. He said yes, since there was no word on my current order. So i went in and configured the new order and the dealer submitted the change in their ordering system. I finally got my production number on 6/27, so it took 5 months just to get a production number.
Your order honestly seems lost. I would first call the dealer, and ask what is going on with your order. After they say some BS like "we dont know" or "still waiting", call 1-866-ASK-MINI. Tell them how long you've been waiting and what the dealer just said. When i made this call after 2 months of waiting, they said only the dealer can get the production number. But they also said i could call MINI back if still no word after another month or two, and MINI could reach out to the dealer to assist me. When you call and tell them how long you've been waiting, i think they would realize something is wrong, and try to help.
