Bajaj Finance — cannot get noc.

I have paid the dues and the emi's and everything, but still i haven't got the noc yet.
I cannot download it from the website, i haven't received it my registered email-id.
I have sent an sms also, but in reply to that, it is saying that my loan account is still active whereas i have received a mail mentioning that my account is closed and i can download the noc from the website, but it can't be downloaded. I have tried a 100times.
People from this company are calling me and saying that they have lodged a complain against me in delhi court, and that i'm a fraud.
This is what the customers get after paying all the amount?.
I want my noc emailed to me asap.
