I also closed my uni account and asked for noc....
Then after many follow ups , they sent an email , which stated that as NOC and mentioned that my Loan Account is Deactivated with no dues . Is that sufficient as NOC?
It usually takes 3-4 months to show up after noc generated in your case, mail uni with the noc and pdf of your latest credit report and ask them to update the closure on cibil.
