Announcement Apps

I recently allowed my daughter to use my Android phone. She is no longer using it but I am still getting her calls. You have to jump through unnecessary hoops to change numbers, I am looking for an app which will announce she is no longer using this phone when it ring.

My name is Kazie and today is the first time I have posted on ANDROIDPIT forum. My initial post concerns an app which will announce that someone is no longer using this phone number. In advance, thanks for any input.
