I have also the bad experience yesterday.
I'm invistigating now how we can complain to ministry of education as I know there is an office for cmplaining about the bad performance and function of private schools.
Ministry of education should follow up this type of schools, it's not allowed to take peoples money and give them back bad answers and management.
that email adres is nonsense, if the principal is not able to solve school problems she have to leave her position for somebody who can.
