MissAdventureI hope they do. If not I would say ring them and insist on speaking to the head. If they tell you she's busy say you will stay on the line (effectively blocking it) until she can speak. It sounds to me as if there is an admin person there who hs been put there to block access. These people are quite often little despots and regard it as their duty to keep anyone away from the head. Great advice above.
Try to stay calm although your emotions must still be so raw. Your family have been badly served. You deserve an apology and the school needs to make sure it never happens again.
