I didn't contact them. It was only noted by Prometric that I had lost time due to the test freezing on me. After restarting my computer I was able to answer the other questions.
Do they send results at a different time if you fail? I haven't received my notice for survey either but I got seismic earlier today. Also, I had my test freeze on me for surveying and lost time; if they are taking longer for that reason??
