Someday, I hope Customer Service is as important to Elon as the farting app. Until then, dealing with Tesla post-sales is an exercise in frustration.
When I took delivery of my car, I was waiting in the lounge while my Delivery guy went to check out my trade. An elderly man came in grumbling about never getting his tags -- for months. He'd grab any person wearing a Tesla shirt and complain and they'd say, "You need to speak with someone in Delivery, but I don't see anyone. Why don't you call and leave message?" Over and over. I began thinking, what kind of service is this? They knew Delivery was on the premises (my guy), but they were blowing him off.
Right now, I'm struggling to get them to make me whole on my deal. They didn't pay off my trade for two months, so I had to make two additional payments. Instead of paying my bank (who held the note) what Tesla agreed at the time of sale, they had the nerve to get a new payoff number, which is pretty sleazy. I raised hell with my delivery guy and he said, "They are aware of the issue and they'll fix it". Weeks later, it became "I don't have an answer, but I'll check." Now my calls and emails go unanswered.
My advice is to just start showing up and be disgruntled in the showroom. Yes, be THAT guy. That's what I plan to do.
