To close the loop on this, in case either of you are still waiting, I called the main US sales number about 30 minutes ago and spoke to someone who took down my information and said he would "pass it to the team looking into these". Within 30 minutes of hanging up I got my email and the RN now shows up in MyTesla with a reservation date of 3/31.
Thanks for the advice!! Did that today. After the phone call, about an hour later I got all I needed. Turns out there was an email typo (extra character). Email address is non-existing. All good now. Customer service on the phone was great. No worries from me. Typo's happen....
