They certainly don't appear to GAF about customer service. Though successful, their business model is a strange one. They pride themselves on the buying experience but honestly it's kind of shitty, afaic.
My local Tesla store has no vehicles available for test drives. Tesla doesn't have dealerships so they don't have salesmen. Any time I go there all of the employees are in the back yucking it up. What exactly do they do? How do they not have time to answer a simple question? It makes no sense to me that I've waited 2 days and counting for a reply from them. I don't mean to interrupt their busy day, but sheesh, you'd think spending $65k would get you a little bit of attention. Hell, the $250 deposit alone should be enough reason for them to reply to questions. I've never had to beg anyone from Audi/BMW to get back to me. I haven't even got my car yet and I'm already planning on replacing it with an A6 Etron in a couple of years.
...maybe I've just been spoiled and have unreasonable expectations...
