Someone put a Screentime in my phone…

Hello community,

I want to ask you if there is a way I can disable a Screentime if idk the Apple ID that was used to set it up?

To give you a little bit of context, I’m pretty sure it was my boyfriend. I’m not able to stop sharing my location with him and actually when I try to use Waze or Uber Eats it does not let me share the location with the app, so I can’t use any app that requires me to share the location.

I’ve talked to him but he says I have to learn how to use my phone because he doesn’t know what happened, he knew my passcode and I’m sure when I left my phone with him he took advantage and did this, I’m sad because I paid for something unrestricted and now it is totally restricted because of him…

please help me.
