I am a teacher and I am appalled. So many things wrong here. It all doesn't add up. You and your husband need to book a meeting ASAP with the principal, the head of prep and the classroom teacher.

Go into the meeting with a list of things you want discussed and write down all the details. Write down what they are saying as well or ask for someone to come in as a recorder.

So sorry your family and DS have gone through what you have so far in his education.,it s not a great example of what the system has to offer.
