Horrible Compensation Mental Exam

How do you go about reporting an examiner? I had my secondary anxiety exam a few days ago and it felt like I was being integrated instead of examined. She asked me questions that had nothing to do with my anxiety and it was very frustrating and I got irritated but I stayed respectful the whole time. Then in the middle of the exam she walked away to do something around the house . It was a virtual appointment. I never felt so uncomfortable in a exam like that before and I feel that I won't get my secondary service connection because of the horrible exam. Any suggestions
