Maruti Driving School — unprofessional manager and rude behavious by management

Hello...i.joined maruti driving school dwarka.sec-5, new delhi...on 17th june, 2015 ...the management has been very unprofessional especially manager and senior persons. I had to call them.again.and again so.that i.can.get the driving.classes.Now.my practical.on road classes have been.over.Iam not feeling confident.So i requested them.to.schedule an.extra class.but.they.simply.denied by saying you.have to.pay 500 rupees. Maruti is.a.big brand but.the.management.is.very.greedy and.they.do.not support.the.customers. I will escalate it.higher authorities.
