Hi, i have registered for NDNC long back with my servce provider Reliance (CDMA) and it was working fine.But, since last 2-3 months i am getting frequent unwanted Tele Calls and SMS from banks, insurance agencies, stock broking, etc, etc. while i am busy at my workplace or home. They ask me for schemes, loans, investments, demat acounts which i am not at all interested in. Few of the names i remember are Angel broking/Sharekhan/Reliance capital/ICICI. Mostly the calls i receive are from Mumbai and Delhi.Kinldy help me how to stop these annoying calls /sms.
