Consumer Redressal

Few days ago I took admission in a Civil Services Coaching Institute and paid the fee in advance through a Bank DD. But due to some reason I do not want to join the institute now and want the amount that I paid as fee back, but the institute has asked me for 30 days to take any decision regarding refund of the fee that I paid there. I haven\'t joined a single class of the fresh batch to begin on June 21, 2014. Kindly give me the suitable guidelines regarding what can be done now in this case and take the right decision.
