Update: So recently I went to meet the principal & the teacher. I ask them why & what happened. Apparently that teacher tak mengaku tarik rambut my kid. She said she didnt do it. I ask for cctv recording, principal said tak nampak that things happened dlm video (which kinda expected, siapa nak buat bnda salah dpn cctv kan?) tp tak tunjuk pun recordingnya
