Hello Larry,
Thank you for contacting the Microsoft Community.
It is unusual that the proctor terminated your exam despite you had clicked the break button. Allow me to provide information to help you with this concern.
Regarding the restroom break kindly check our Unscheduled breaks on exam policy for reference, and steps on how to properly execute breaks to avoid having the exam cancelled.
Also, since you have already reached out Pearson VUE, and a ticket has already been raised, allow me to request your case to be prioritized. To do this, please supply the information requested in the private message for us to locate and verify your profile.
If you wish to submit feedback regarding the experience you had with the proctor, you may go to Feedback and complaints | Pearson qualifications and fill out the form. This will help Pearson VUE improve their services, especially in online proctored examinations.
I look forward to your response. Please note that if no response is received after two business days, the case will be closed and locked. After the case is locked, we will no longer be able to respond, even through Private Messages. Thank you.
Best Regards,
