I will call the pre-school and speak to the principle next Monday morning. I will highlight the issues to the principle, as I feel that other students are in risk too. I certainly feel that other mommies wouldn't want this to be happened as well. I don't want other students to get hurt (touch wood).
Now, come to the money part...I wonder whether the principle will make full refund to me or not, due to my cancellation. Ok lah, if she still wants to charge me on pro-rate basis, go ahead. But even if she's so tamak haloba and refuse to refund to me, aiyah...take it lah. I'll spend lesser next month, to cover up the loss. Now got Mega Sales, sure can spend lesser what :P
