I had a very good experience with Tesla insurance and Tesla Collision Center in Dallas. Both handles the claim in timely matter without any problem, status are updated twice weekly, I don't ever have to worry about what's going on. I think Tesla expands their collision centers by buying some local companies and retained their staff, you can also walk into the shop, live person answers the phone, it makes all the differences.
Contrary the person that replies on the app can be clueless, making things up, rude, they are not evaluated and those positions likely disposable and turn over quickly.
