[Resolved]  NIIT — no response from niit south ex, new delhi

I have done my gniit course in 2014, i was transferred from niit, palampur hp to niit south ex., new delhi. I have doposited all fee and documents at niit south ex., now i wants to take my certificate. When i call to niit, south ex., new delhi, they don't pick up my phone. I tried many time but they are very careless persons. I am raising my complaint here and hope this issue will be solve from their end.
