What do I do?

Discipline - I had a teacher bring to me after school yesterday a concern between Levi and another student. Both of these students have already been given directive to not have any more contact with one another. There has been various items said to another student and also a social media picture of the other student and written on his back is Shitstain. After discussing this with Levi, he admits that he has tried to stop with said student but just hasn't. I explained that since I have already told him to stop these behaviors and there is continual verbal and social attacks towards the student that he will have In School Suspension today. I also told him that if anything else continues that it could lead to out of school suspension and especially if there is a physical altercation it would lead to charges and possible expulsion.

This was a write up I received today. I am currently in ISS. I'm worried about going home because they called my Father. I don't know of any way to get out of this situation...any ideas? Other than..."face the consequences". I need something to say to my father to get out of this.
