Has anyone changed their order via phone call/e-mail? If so how long did it take for the config change to come through on the website? I live in southern California, non-owner, reserved 12/25/17, configured AWD 6/29/18 (Sep-Nov delivery window), and then called on 8/7/18 to change to P-AWD. They suggested I do it via email so I sent email to change order same day (10 days ago) and even after a couple phone calls since then including reassurance it is gonna happen, manager contacted, etc. website still says old order config. Have been told by multiple phone reps to not change the order online so that they can 1) ensure I don't get extra fees for changing 2) ensure I get free supercharging/premium connectivity confirmed on the order, but it seems like I'm sitting in line for a car I no longer want while not in line for the car I do want, and I just worry the delays could push me past the end of the year for delivery. Maybe I'm too worried? Just aggravating when everything is so...unclear.
