Scam or fraud: Central Board Of Secondary Education [Cbse] — maths re- evaluation

Sir i got the photocopy of my maths ansswer book but when i verified my answer with the marking scheme of cbse. I found that there are few areas where i havent got marks that too according to marking scheme. I should have got 13marks more. So i applied for re-evaluation in 6 ques. But today when i checked the cbse website i found that no mistake found. I was like are you kidding. I verified with my friends and my teacher and clearly there is an increase of 13 marks. I want justice
My roll number is 2629921
