Who promised you this? SAs? Tesla has never straight out said “upgrade your 21s and you get your car sooner”. Hell, we are seeing people upgrade to 21s and still sitting at October.
Offered. Not delivered. You still have the option to wait for carbon fiber and get what you ordered. They are delivering it, look at deliveries. Not at the speed any one wants, but they are delivering it.
Who “convinced” you? You have the right, as the customer, to say no. You also have the right to “settle” (In my opinion) or accept what is being offered versus waiting for what you wanted. It is not like Tesla has a gun to your head forcing you to take delivery.
As I said earlier, everyone is (rightfully) pissed off about the delayed, the process, the sequence of cars being delivered. But stating it is a bait and switch is wrong. Also I said, if you were bait and switched, take the legal course. Hopefully you remember to opt out of arbitration.
