School Fees Refund

My child attended school at ST Jeff College. The principal is so rude. He suspended a few kids because their hair was not cut, I then decided to take him out of the school end of July and found a new school. I had paid the school cash which was R10900. He promised to refund me, but till today I have not received the refund. When I call they tell me his not in, when I went to the school , he said payments are done end of the month, which was supposed to be end of August but still have not received the money.
