D-40,Sanjay enclave ,Uttam Nagar ,New Delhi 59, New Delhi, Delhi, 110059

My ward is studying in great mission public school, d-40 sanjay enclave, uttam nagar, new delhi 59.in class 7th. Today my son told me that his school principal ms. Radha ghai misbehaved and used abusing language with class 7th kids for not paying fees balance and kids were very affraid of her that if fee will not be payable by parents in time our principal will not only give us punishment but also she will slap them 3-4 times a day, even though they are torchering and gave warning to the kids that we will not give you result at the end of the session and you will not be able to sit in the rest of the exams.
My son is mentally tortured by the school principal. Not only him but his classmates also, he is in mental stress he is not willing to attend the school anymore as these days exams are going on, what should we do? What if my son wouldn't be able to handle this mental stress? Kindly acknowledge this in priority basis and take some necessary action for that. This is my humble request to do the needful to save the future of the children. I need action and reply as soon as possible as this is the crime against education for children as per the government education law.
