Thank you for providing the additional detail. In this case, this is not issue with how breaks are being implemented as this happened before the exam began. The actions I would take to solve the break issue are very different from the actions I need to take in this case. This is why it's so important to escalate these issues to our support forum so that we can get the necessary information to take the right actions. It sounds like this was escalated to Pearson, but did you escalate to Microsoft? If not, would you?
In the future, if you don't get a response from Pearson, please escalate to our support forum with the details of the actions you took with Pearson. If you still don't get a response, you can contact me directly through this forum (send me a private message as I need details like your name and registration ID).
Thank you.
