I am so sorry that you and your daughter and family are dealing with this.
I myself would tell the police if someone made that fake $200 order to my house. The police especially need to know of this issue if there is a possibility of a fake SWAT team report. The pizza shop is also being harassed and perhaps their phone records can help the police locate the caller.
I would also tell the school. Idk if they can help but word does get around, kids brag...
