Buatkan contoh surat complaint letter yang ditujukan kepada sekolah

My daughter, ABC, is a student of class IX 'A' of your institution. I have already met the school guard and his supervisor, who are totally unaware of the happening, which is highly irresponsible on their part. Furthermore, I have also spoken to her class teacher, but the matter is still continuing.

As this is a highly serious and unacceptable issue both for the students, as well as the school authorities, I expect a speedy action from your side. If required, I can meet you personally and accompany you with the written complaint signed by all other parents to seek police help.

Awaiting a positive response at the earliest.
