I would suggest, just for sport, to ask them about the trunk and dashcam issues that they will introduce by upgrading you to V11
Hopefully thats a joke... but if not, dont do that (unless you never plan on using that particular service center again). If people think that those in the service industry dont remember people who are "difficult", they are mistaken. They absolutely do remember, and will ensure that for those people they only do "what is required" (not "what they are allowed" which is usually not the same thing).
This is all service people, in all industries that provide service. The "old person" saying of "you catch more bees with honey than vinegar" still applies, and will continue to apply, until humans are removed entirely from the equation (which tesla is absolutely trying to do).
Computers dont care if you are nice, nor do they make exceptions (which is why tesla is always pushing people toward the computers / apps etc..)
The OP has already marked themselves as "a difficult customer", otherwise there would not have been the note on their account that they mentioned:
Also mentioned in the notes that “vehicle should be towed out of the service center” since customer declines firmware update for a safety concern.
The software version is not nearly as bad as people say, but still, this is OPs prerogative (just like it is teslas prerogative to deny fixing the seat since they wont take the firmware update that will allow the seat to get programmed to the car after installation).
OPs choice, but making the wrong choice will leave their account marked, for sure.
Note that I dont have inside knowledge of tesla in this, but I do have inside knowledge of how customer service organizations work. Its all very similar.
