Absolutely fuming on your behalf. What a disgraceful reply. Ok, so maybe they have misunderstood your first query, about the waiting list thing, which would explain point one, but the second thing ... there's no misunderstanding this, it implies that your daughter isn't popular (WTF would they know?), that bullying does go on or has gone on, that they allow this to happen, and that they are a very non-inclusive group.
I'd phone but I would also send this to the regional/national head people to show exactly what you received, I would also inform them that you are sending it to the local press, because this shouldn't go unnoticed.
Off out now but do let us know what's going on. I am so cross!!
