Airtel
Getting promotional sms after registering for DND

My Airtel mobile number was registered with NDNC (Reg. no. W1026977595) on 4th January. The sms following the registration said promotional calls or sms would stop within 45 days from then, but to my utter surprise, till today, 21st May, '11, I'm receiving these types of sms and calls. Also, when I went to lodge my complaint in their site (http://www.airtel.in/wps/wcm/connect/airtel.in/airtel.in/home/do not disturb registry/), I find quite difficult to submit that. Everytime, after giving all the information, i.e. phone number, date, content of sms etc., some bogus message coming, saying "give today's date or past date" etc. and don't let me submit the form online. As a matter of fact, I was then complaining about the present day's sms or phone.

This is the case. Please help me what I can do next.
