ICICI Bank — noc not issued again credit card settlement

Address:

Jaipur, Rajasthan, 302021

I settled down my credit card with icici bank with settlement no no. S[protected], dt.[protected]. It was settled in 25, 000/- (Two installment: 12500 each) & payment was done via cash deposit in bank. Last payment was deposited on[protected].
Per mail from icici bank it was mentioned in settlement letter as"once final payment done zero balance statement will generate in next fifteen days from date of payment and ndc will be provided", statement is showing total amount due on[protected] is zero but cibil is also not updated & showing as active.
Tried to contact mr. Negi (Contact info given in settlement letter) but not response.
Followed up over the mail to but no response from icici bank.
Looking for positive response.
