I joined an institution called DDA affiliated by MDU Rohtak for mba in 2012 since then till now i havent recieved any semester marksheet recently i have given my last semester exam. When i asked for my results they said you havent attended one of your exam thats the reason your all marksheet is on hold. they asked for 1000 rs for one paper for reappearing in exam i have paid them still didnt get my result. again in last semester when 2 days left they asked us to submit practical papers of 500 pages. When we asked them how we will do it They said that we have spoken to the examiner and they are saying you can pay 2000 and you dont have to submit practical. somehow they aggred for 1000 . otherwise they were sayin that they eont give us time nor marks. please help me? Since then i called The college dean almost everyday but he always says we are working on it pleae help
