I had an issue with a well known app for taking online exams and ended up having to call the French technical support. I had no proposed troubleshooting whatsoever from the lady on the phone and she kept on arguing about general software/ operating system incompatibility. Later I could find out that the issue related to another component of the laptop, having nothing to do with the operating system and that could fix the bug. So disappointed by the time and money wasted on that call.
