Refund of admission fees from engineering college

Sirs, My daughter got an admission for B.E in a engineering college by counselling of anna university, Tamilnadu. I paid entire fees amount [Rs.108500/-] on 07-8-2017. The college declare that the classes will start after 20-8-2017. In this situation on 08-8-2017 my daughter got a chance to join in an another college which is nearby my town and mostly liked college by my daughter. During counselling there was no vacancy in said college to select. I admitted her to the second college on 10-8-2017. Hence i approached the first college to refund me the paid fees amount. First they denied. Thereafter they demanded me to write a letter to them duly stating that my acceptance to receive the balance amouont Rs.58500/- after deducting Rs.50000/-. Also they informed me that the balance amount will be credited to my bank account shortly. The admission of students in first year B.E is still going on there. I want to know whether the college can collect Rs.50000/- from my paid fees due to quit from course. Kindly guide me how to act further.
