Need some assistance

So today i took the assistant conductor trainee test. I was 100% positive that i passed. I felt confident about it, took my time and all the allotted time that was given. I was one of the last 2 ppl in the class and i knew that i had took the time and did it the right way. Even the test host verified my name once i said im done and told me i passed which im assuming he wasnt supposed to do but he told me i passed and congrats. I waited for the official email to come in and the email i received stated unfortunately i did not pass. Now even if the host did not privy me to that info i was sure i passed. Is there anyway to contest this or get them to reassess that final outcome because i believe this was done in error. Someone pls assist
