Refund of fees from coaching centre due to poor quality of education

I am a student. i paid fees to the institution for DSSSB. I dont want to continue with that institute because of poor quality of education they are providing. At the time of admission they said they'll arrange their best teachers in any circumstance but now the owner of the institute use to take classes by her ownself and qaulity is too poor. it has been 2 months now m asking for refund ,she is saying she'll not refund my fee. Their teacher always use to point out me in class. He pointed me out for my dark circles he never cleared my doubts. it possible to get the refund of my fees.
