Ryan International School — Fees not refunding

I had enrolled my child in ryan international for class 11 ISC in goregaon Mumbai but later i wanted to withdraw the admission as i was getting admission in a better school, but as i said them to cancel the admission and return my 10, 000 rupees which I paid as the admission fees they just reply by saying we will revert back and they haven't yet and it's already been 2 weeks, i had also send them the receipt and everything but they would not reply when i said them i will take the legal route they started removing my fault
