I write to alert parents of kids going to pcf. If you are unhappy about the school and teachers, complaining to MOE is useless. At the end of the day, they side each other.
Unless you have evidence captured in camera like the little skool house teacher who broke the kids legs - then they will only sack the teacher after many months of investigation.
My kid was abused in PCF blk 1 serangoon and i know how they handled the matter.
