After that he said me to pay the booking fee of Rs 15, 000 after paying that he asked me to pay Rs.2000 for the emi processing fee after that he asked me to pay Rs.2761 moritorium fee and I asked about this and he said this is one time fee only after placement you have to pay remaining amount. But I paid every month Rs2761. now I failed in one subject in my final year and my father is also not feeling well I want to feed my family so I joined as maintenance engineer for Rs12000 with the help of diploma if I pay the emi of Rs.11000 how can I feed my family and I can't understand anything form niit. So I am begging you to cancel my emi please understand my situation. I can't pay the emi
