I decided to join pgp course at niit, madurai, tamilnadu after getting lot of counselling from branch head of particular branch during time period of oct, 2018. And decided to join on nov 23, 2018 on the basis of assured placement. They told me that time duration of course will be 3 months. But they didn't complete my course with in a time. They force me to pay the fees within the time. I paid the amount properly on time. They are not conducting the class properly. They didn't pass the proper information about the examination date. They extend my course nearly 10 months. After a long struggle, i attend my last examination on july 5, 2019. I received the message as, "visit the corresponding center to collect the certificate on or before july 13, 2019" regarding certificate. So i contacted my center, they didn't answered properly. Please, i request you to take a necessary step to provide me proper service and give me some placement oppurtunity also.
Thanks & regards
