You got shafted dude. They didn't place your order with a dealer for a long time after you placed your order with them
As soon as I gave the email go-ahead, before I'd even signed anything, my broker reserved a build slot with the dealer. It was literally the same day I said "yes", they gave me the thumbs up from the dealer. I placed my order on Aug 17th, a week later than you, and got a build date in October and a delivery date of the second week of November so if you placed your order week before me and are getting your car a week after me then something is fishy.
These people sound like cowboys to me.
