did you send your email to candidatecare@nasba.org? I think when it happened to the girl I knew she contacted Nasba by phone (866-696-2722) with her NTS (exam id), test center location, exam section & exam time, and told them she thought she exited out of the exam, and they were able to verify that she was fine (she didn't tell me more specific than that). AICPA will only take content related problems that happened during your exam & it has to be reported by fax within 4 days of your exam.
I am IL (independent) state so we contact IL state board for most of our issues. I am guessing you are a Nasba state. I have heard of a lot of candidates that call them twice to get a second answer when checking about scores. If you are an independent state I would try your board. If not, try to get a second answer from Nasba. I wish I could be more help. It has to be awful to think you might have exited out and then have to wait to find out. I wish there were better lines of communications open to us for issues such as this. In Jan/Feb I called my board and they told me if they didn't post my score, they didn't have it. I called Nasba, and they couldn't help me because I was a board state. It's very frustrating. I hope someone can help you further just for some piece of mind that it is okay. My score was held in Jan/Feb for audit hostage a few days shy from three months due to new sims. Could you have had new sims? If so, you are auto held to the second wave & that maybe why they don't have it yet.
