Jacko,
I went through the same thing trying to get the SC in Jacksonville to pick up or return my call to order the TPMS. I dropped by in person, went inside to an empty lobby, and checked in on a tablet. In less than 10 minutes a Tesla service person had come out to the parking lot and asked how he could help me. I ordered the TPMS and said it should only take about a week. This was on the 3rd and they have not arrived yet, but I do get email updates from Tesla twice per week.
If your SC is nearby, you might want to give them a visit.
