This is an update to my post. Thanks to all of you, I reached out to Jon O'Neil. He responded within mere hours that evening. By the next morning, someone who worked for him contacted me. The parts were promptly expedited. Unfortunately, a mismarkrd part was shipped. It took another week to get the new part. In the meantime, tesla arranged for a loaner for me. Tesla's heart is in the right place customer-service wise, but they do seem to have kinks to work out of their system. I finally have my lovely new car back.
