So my mom's phone was stolen today and she wanted me to sign into Facebook for her on her new phone. We keep forgetting the password but usually just use password retrieval. But this time i got in Facebook, typed in my mom's phone number and it logged me into another person's facebook. It says the number of this Facebook was just changed to my mom's number idk how tho. So now my mom's Facebook does not have a linked number or email to use password retrieval on. Please help.
