To try to steer back on topic, and especially for anyone joining late, the OPs concern with Tesla - as posted on TMC, in my view - can be summed up with both an overly demanding customer and sub-par sales experience with both his P85+ and P85D, a totality with ended up totaling the OPs and Teslas relationship. A sad story, really.
In both cases OP claims to have been promised things that didn't materialize and felt misled and pushed hard by sales on choices he didn't prefer (allegedly was waiting for AWD Tesla but got pushed by sales into P85+ on the account AWD wasn't coming anytime soon - and then it did upon his delivery - and later after taking a hit on that, receiving P85D with wrong seats and not being told about it or easily allowed backing out from the sale when he wanted to). From Tesla's complaint management perspective, who may have well been unprivy to the sales-person level experience, he was a difficult customer that they felt was unreasonable and seeming costly (allegedly making unreasonable suggestions as to how to correct the situation and feeling somewhat litigatious), so they cut ties and the OP hit TMC.
It is very hard to say what the actual on-the-floor fact may be, but the overall story - as told on TMC - is far more complex than just one difficult customer.
I think Krugerrand's own quote is actually very pertinent here: "It is not the responsibility of the customer to babysit the professionals, or to go in there treating them like they are children laying down ground rules that are clearly understood by the virtue of it being a business." If Tesla's sales people made mistakes, surely Tesla is responsible and probably, generally speaking, their status as the company and the professionals demands a bit more of them than of the consumer. That said, we can also debate
what the correct response is from the consumer side as well. Not any response from consumer is always warranted either.
I think both parties probably are at fault to a degree - and I agree the OP probably didn't approach the issue very wisely, thus making thing worse.
In any case, an unfortunate story.
Also, some of the thread debates whether or not companies should be within their rights to blacklist customers, when they control the entire sales channel - and whether or not that could be an argument for the dealership model and lot purchases.
