Aakash Institute — not refunding money and security deposit

My daughter joined the institute on 16 july and stopped going on 18 November due to poor education and management help . We took 2 year course and i payed 125000 to akash institute through a bank loan . I was told by the councillor that my loan and akash fees will both stop if i write termination letter but it didn't happened and now, i have to pay every installment of the loan even when my child is not attending classes . I have asked for refund but they refused .i belong to low middle class family and i want my money back.
