Hacked phone, no matter what I do always the same

So I have this Moto g7 play Android phone running on 9 pie. Not even sure what that really means but my phone is hacked and the few phones before that were hacked into also I've changed phones, phone numbers, and phone carriers even went through a whole lotta different Google and Facebook accounts always same result. How I always know is the phone regardless if where I am it always says I'm in Pennsylvania however I've never even been there I'm pretty sure I know who is doing it but the real question is. How do I make it stop and reclaim my phone and really my life too
