If your score card has your Category mentioned as General Category instead of OBC, there can be only 2 valid reasons:

1. You entered the wrong Category and didnt correct it during the correction window
2. NTA must have committed a technical glitch

Now if it is the first one, there is really nothing can be done. Ideally if the Community that you belong to is listed in the Central OBC list, then you can avail OBC benefits at All India Level. Or else at All India level, you have to opt for General Category and then at State level, you should opt for OBC Category. Even this is fine. .
