Tesla has some of the highest customer satisfaction scores among car brands. I'm not sure what you are referring about "tens of thousands of angry customers", you need to look at percentages and not absolute numbers. Tesla has had quality issues and problem with services but overall people are very happy as far as car brands go. And you have to be reasonable with your expectation for customer service of an internet service provider. There's only so much you can do to help an individual customer. Maybe it doesn't work in your area for some specific reason, you can't expect their engineers to spend time investigating that single case. If it was a broader issue i'm sure they would look. Did you try getting new Starlink receiver?
