Grandparents locked a girl in the bathroom for 6 years?

Summary: This story is about a little girl who was locked in the bathroom for six years by her grandparents since age 3 to age 9. She would eat sometimes but not all the time. She would sleep in the floor with one blanket but no pillow. Once she came from school she would go in the bathroom and would not get out until the next day in the morning to go back to school. They locked her up because at the age of 3 she had bad behavior.
