Oda class pigeon education pvt Ltd - Long pending refund

I had enrolled my son for the Master Program of ODA classes for Std. * on **th March’** and paid the fees of Rs **,***/- but due to some other schedules, we cudnt continue. Hence, applied for cancellation of his enrolment and refund of fees paid within * days. I have been following up continuously since then through mails and calls, but have always been asked to wait a little longer. Now *.* months have already gone by neither the refund is processed nor are they answering the calls or emails.
