No Network Coverage

I am residing in Bangalore (Res - Rajajinagar, and Office - Richmond Road). My bsnl mobile connection is showing no signals 'No Network Coverage' in these two prime localities also. The problem is persisting since 3 days. I lodged the complaint and got the ticket number. At the time of lodging the complaint, I was told, the problem will be rectified within 24 hours. On subsequent follow-up, they are telling within 24 to 48 hours.
