<PLEASE HELP>A weird thing happened to me while starting my GMAT Online.
Got a BLACK SCREEN with a slider at the top with two options CHAT and Online Whiteboard something (I was not able to click either of them). I tried speaking to the laptop but no one was responding (weird

). After around 20mins of wait and staring at the black screen finally got a call from the proctor (voice quality was like the 90's customer support): asking me to wait for the next proctor and click some button. I explained to her that I cannot see anything on the screen: it's completely black. She said to wait and disconnected the call. After that, I waited for around 50 mins nothing happened so I finally restarted my device.
mba. com profile is showing my exam as pending. I have raised a complaint with the online chat option as calling customer support is not an option during the weekends.
Can anyone please help if you faced such a similar issue?
What do I do now to get GMAT Online exam and score ASAP as R2 is pretty close?
