Mumbai University — wrongly marked as nri

Address:

Mumbai City, Maharashtra

So i have applied for post graduation admission, i have applied for few colleges and when i tried to submit the application, i realized that i have been marked as an nri, this form was filled in 2015 and it cannot be edited again. So what should i do? Should i make a new account and a new profile or should i approach the mumbai university? I have been trying to call on their helpline but they aren't picking up and it's being said as busy.
