Barry...Jesus. This guy is killing me. Why couldn't he have checked into this BEFORE he ruined my day yesterday?
Many of us (customers) have been asking for Tesla to step up their communication to (push) proactively let us know when "things develop" rather than only tell us things when we call to ask for status (pull).
Here, Tesla called you to say "Hey, we might have a delay here. It's unfortunate but we wanted to let you know so you could adjust your plans accordingly."
This is a good thing. It should be appreciated not attacked.
I realize it's stressful waiting for a car you wanted the day you put money down (and we've all experienced that kind of stress, except perhaps the folks that bought loaners/test-drive vehicles) but your reaction kind of supports those that might grimace and say "the customer may be 'always right' but there's no pleasing some of them."
Please don't provide feedback here to Tesla that motivates them to go back into "say nothing" mode like they've done in the past all too often.
