Scheduled an online exam. Passed the system test, but the OnVue app got stuck at "loading..." even after rebooting system and trying all sorts of suggestions mentioned online to fix it. When I finally was able to launch the app, it was 15 minutes after my scheduled time and I was not able to proceed.

I spent 45 minutes with the online Pearson VUE support, repeating questions over and over, which were just dodged. I was not provided with any assistance whatsoever. The representative, Doe, briefly filed a "case" but refused to send me a confirmation e-mail of the case. Moreover, the Doe declined to confirm in writing that she or he was unable to help me log in and take my exam.
