A hacker is breaking into my facebook and much more?

As Mba Expert says, you need to change your phone number and put that number on as your Facebook sign-in. You also need to change your passwords to every account you have. Don't use anything that someone with your personal information could use to figure out. Make the passwords something random.

An IP address in Michigan means nothing really. That person could be using a proxy server.

Call your phone service provider and see what can be done about disabling the phone remotely. It can't hurt to ask.

I know this is 20/20 hindsight, but your mom should have agreed to give that guy the $50 and had a police officer with her when he came to collect.
