Refund of fees from nursery school

Hi, I went to one of the nursery school Kandivali branch on date 5th May 2017 for inquiry of nursery admission. On same day I have given cheque of 15000 . I received admission form and advised to fill it and submit with some photographs of my daughter. Meanwhile due to some uncertainties we have neither filled the form nor submitted the same to branch. Now due to some issues we are not able to take admission of our daughter. In the same context I am requesting for refund of 15000. School is not agree to refund the amount. I have submitted written request to them as well, after that the owner called me and rejected for refund. I have recording of that call as well. What can I do to get my fees refund?
