Address:

I am student of class 11th of K.V sector-12 dwarka. I want to complain about my accounts/business teacher name Mrs. Poonam Malik who keeps on slapping whole class for no reasons. she dont take any interest in teaching us but she keeps slapping students. Because of her behaviour one friend of mine has left the KV Sangathan recently. I want to request that please take some hard actions against her as soon as possible because it doesnt only disturb our studies but also disturb our mind.
