Your family issues were not the problem of the school. I know this sounds harsh, but it is reality. They are running a business.
You might want to check whatever contract you signed for the school, but I doubt you have a legal leg to stand on.
It appears that you were demanding something that you werent legally entitled to.
The school did provide what you paid for, but YOU left! YOU broke the agreement, not them.
And, STOP with the spouting or the "class action lawsuit" thing, as it just makes you look stupid as you obviously don't know anything about how difficult and costly they are.
