Adhoc requests

What does Alexander Forbes assist with excatly when it comes to the trust fund of a child. I am unemployed mother and my son is allocated R8k for the year. R4k was paid January for stationary and some was used to buy some of summer uniform. Now in May I requested money for winter clothes and was told money wil pay for his school fees. Which is fine, but is he not entitled to get clothes? His fees is 950pm transport 800pm. How far does 4000 or even 8000 stretch? All they see is a money hungry mother who wants to abuse his son funds. So what is the adhoc request for basically if you cannot ask for clothes? Last year they did not want to pay for school fees, transport, clothes. I had to involve umbudsman. Why should everything be a struggle?
