JEE MAIN Request for checking my JEE MAIN paper again

Request for checking my JEE Main paper again
Sir, I appeared for JEE Main online exam on 15 th April 2018 . According to the official answer key I was getting 40 but when the results were out I got 24. I am sure that there is some mistake with the checking of my paper. I request you for the rechecking of my paper. I am already late, please do this as soon as possible as the JOSAA counselling is going to start after 6 days.
Thanks

Sincerely yours,
