FCP_FGT_AD-7.6 Exam PearsonVue Issues

I wrote a Fortigate Administrator exam the previous week, and mid exam my pc restart and I had to login in again to continue but I was unable to continue because the Exam did not want to open again, the pearsonvue app was only showing the my video, and no chat option was available, after a while I got disconnected from the exam and I was told that I violated a policy when I contact the support team. I am reaching out because I lost my voucher and 200usd for a system that didn’t work properly. Please hep!
