For the most part on two of my 3 deliveries I had the same experience with my DS - however my last one was EXCEPTIONAL. Nick @ Tyco Road and his team were awesome this past Friday, working with me to make sure every little thing was great and when we identified a few small things wrong they asked if they could fix them before I took the car - which I gladly did.
Not to defend poor customer service, which I do believe exists, but you also have to put yourselves in their shoes a little. EVERY person who ordered a custom Tesla is emailing their DS asking for info and, oftentimes, they have the same lack of info that you have. The My Tesla page is nice, but oftentimes behind/off slightly and the DS can only operate with what corporate it giving them.
Again - not defending when they are poor at responding with at least a courtesy note that they have no new info etc, or to confirm they received your date for delivery, etc (or, in one of my cases completely failed to give the SC the list of items that needed fixed so I had to go over it with them four times), but try to understand that EVERYONE is asking them the same questions, over and over, and they are human.
What I have done is, after receiving my vehicle is I will send them an email with a summary of what I felt they did right and what I felt they did poorly - they can’t change anything for my experieince but maybe your constructive criticism can help them become better for the next guy. Copy their supervisor. If they don’t change they probably won’t have a job much longer and their superiors should also work to make sure the process is better. When I was frustrated about the lack of comms between the DS and the SC folks, I send a note to the DS, his supervisor, my OA and the SC manager with a calm, meticulous timeline of events.
The OA made calls, the SC Manager called me and, from my last experience just 3 months later the process was better.
Again, not disagreeing with your frustrations, I share them, jsut trying to make a suggestion of how to make it better for the next guy.
