Kendriya Vidyalaya Sangathan — Immoral behaviour of teacher

Address:

2nd 68-E sleeper ground railway colony, alambagh

My sister has been studying in KVRDSO LUCKNOW in class 11.There is this teacher name Alpana kumar ( science teacher) who was the class teacher of my sister at the time when she was in 10th. My mother went to school for some matter and wanted to talk to this teacher just for 5 minutes.This teacher talked to my mother in a very rude way and asked her to go away.My mother started crying ( she was being too emotional)and then she gave my mother 5 minutes. Is this the behaviour of a teacher????? Parents have to cry infront of teachers just for their 5-10 minutes ?? Do Teachers don't have the responsibility about students in school!!! I request the organization to look after this matter
