Bad school manners

I app**** at the school for my daughter to start 2nd term as we're relocating from cape town. I was told by Elna she has been accepted. 3 days later i was told there's been miscommunication and she not accepted. I asked for the reason and i was told the technical school my daught is at does different subjects to newton TECHNICAL High school. If a representative of the school told me my daughter has been accepted, why is it that the decision has been reversed without proper reasoning. I am sure to take this further as this was unacceptable.
