My DS originally contacted me shortly after I ordered my model S, and I have communicated with him a bit, though the last communication with him happened on October 12th. On October 26th, the car exited production, and on the same day, I sent my DS an email asking some questions about additional equipment and pricing. Previously, my DS has responded within hours, or at worst the next business day. We are now at the end of the third business day since I emailed him, and nothing. Should I worry, and who should I contact? I'm located in Norway.
