Unable to Finish writing online Pearson Exam

Absolutely disgraceful - I was busy writing my online Microsoft PL-900 exam, during the process of answering the first question, the proctor messaged to ask if I was finished with my exam, I rep**** no I am still busy with the first question and by the time I got to the 3rd question the proctor ended the exam abruptly with no explanation, I followed the rules and did nothing wrong and paid R1000 for the exam I was thrown out for, for NO REASON!!!!
