BSNL Broadband
Temporary Disconnect problem

I am a subscriber of bsnl boradband services at Rajkot (Gujarat). I often get disconnected from network at an interval of say constinously for half an hour or some times for indefinite period. While working on internet i always remain under constant fear that just now the connection will lose and drop at any moment. So, the services of BSNL Broadband are always uncertain and not dependable. May i request you to take suitable action under advice to me. My residence phone No. is 91 0281 2576707 and mobile No. 09825826162- Thanks
