Council For The Indian School Certificate Examinations [CISCE] — harassment of my child by his class teacher

Sir/Madam, I would like to kindly bring to your notice that my child Sonakshi Sarangal is studying in 8th standard in little Flower Convent School Sohal, National Highway Amritsar-Pathankot, district Gurdaspur, Punjab. Her class in-charge Gurpreet Kaur has been harassing her mentally for the past one month and fifteen days. On 1st April my child could not attend school for one day due to a sudden emergency in the family. On 6th April, during the parent-teacher meeting, the class in-charge very angrily asked my child the reason for her absence which I explained to her. I told her that my child is not getting some concepts of physics and math subjects, so she said that you should go and meet the physics teacher but asked not to meet the math teacher because in this way he can feel inferior. Since that day, my child is being mentally disturbed in the class by the class in-charge Gurpreet Kaur on some pretext or the other, due to which my child is feeling anxiety since that day. After consulting the doctor, he said that if the child's anxiety is not controlled, it can become a serious mental illness. Taking care of my child's health, I strongly request you to ask the class incharge Gurpreet Kaur the reason for this and stop her from bothering my child from now on.
I sincerely hope you will consider my request
Regards
Pawan Kumar
