Mott Hall Bronx High School

This school waited until 3 days before graduation to tell my son he's not graduating after telling him he passed everything and will graduate. They claim they were just checking their records to find out that he didn't pass some English classes. These classes were brought over from his last school after an incident that caused my son no to go to school because a restraining order on a nothing student.
When I called and spoke to his guidance counselor Ms. Simpson she first says oh you can blame me and in the same breathe say he had poor attendance. I told her she was sarcastic and being condescending and said none of them should go to graduation cause they dropped the ball. Also no call was made that he was in need of these classes when he first came to the school.
If you send your child here please be on top of all their credits and classes needed this shouldn't happen to another student.
Now I have to find a way to help my child get over this.
