NIIT — rude behavior of lady receptionist

Yesterday i went to niit camac street branch to know about the details regarding their courses and fees structure. Today i got a call from them that whether i will be taking admission or not, i said it won't be possible for me to afford such a big amount. Immediately the lady started abusing me without reason saying that before coming here you should have the idea of the couse fees and we won't provide our courses for free blah blah. It is completely my own decision whether i will take admission or not and she has no right to say like this.
It would be grateful if you take necessary action regarding the management of this institution specially that particular employee.
