LOST EXEMPTION ON GETTING REVALUATION/CERTIFIED COPIES.

Hi Everyone. I scored Exemption [63 Marks] on Accounts in Nov 2018 exams which was announced in 8th Feb 2019. I had applied for certified copies for that paper which I received this morning with a mark of 54.5. I'm very shocked to see this. Can this happen for real? Will I lose exemption?

I have already applied for May 2019 exams by claiming this exemption. What should I do now? No one is answering calls in Examination Department.
