Person I Have A Protective Order Against Won’t Stop Making New Phone Numbers And Trying To Contact Me But I Don’t Know Where They Are Located [pa]

I have a protective order against an ex partner. They won’t stop texting and calling me from different phone numbers. I block them and they just somehow get different numbers. Today they finally somehow figured out my address and texted me it. I don’t know what to do because I don’t know where this person is to make a police report. I think they might be with their parents which I know that address/city. Do I call the police station closest to that to make a report? The order was filed in PA and I believe they are in CA. I’m so beyond scared so any advice is appreciated
