Aside from what has already been said, any spell used to harm or control others tends to also cause issues for the caster. The energy you send out, be it positive or negative, tends to come back to you in one form or another.
If you have an issue with this person, I would strongly suggest talking out your problems or moving on with your life and dropping the issue. If it is something illegal that occurred, I would go to the police and let them handle it, that is their job after all.
Life is far to short to spend time hating others and/or plotting revenge because an individual wronged you in some way.
