Perhaps I'm being untrusting or pessimistic like
@zoomer0056 said, but once again this just doesn't ring true. I've dealt with service numerous times and spend a fairly large amount of time on these forums - it's very rare to talk to anyone over the phone at the service centers. Almost all communication happens via the app.
Even if your story about waiting for battery pricing checks out, you could still post your messages from the app... if your car is in service, then you have an open case in the service portion of the app.
Also, when I brought my car in for service recently, as soon as I pulled into their parking lot, my car was within their geofence... they switched it to service mode shortly thereafter without even being in the car and I could no longer see the same information in the app - so how is it even possible that you could know they were driving your car around the parking lot?
Once again... I've driven my Model 3 for almost 3 years and 50k miles. I'm having a hard time believing that anyone who's had one for 5 years and 132k miles (you) would make this statement.
Your post reminds me of a recent EV hit piece I read from The Federalist where they rented a Model 3 for a road trip and had very little good to say.
I'm just saying... if everything you've stated is true, you've got a strange way of representing it... because there are a lot of parts of your story that just don't ring true.
Maybe I'm totally wrong though. You could easily prove it by posting screenshots of your messages through the app.
