BSNL-CELL ONE
UNSOLICITED CALLS

I have been receiving unsolicited, missed calls from from 9049403129 since 23.15 hrs of 10.8.2009. When I tried calling back, the person on the other end is simply holding the line without talking. Tell me how to trace the line and block all his calls. MY NUMBER IS 9422485575.
