Sir,
I have an airtel mobile post paid connection for almost 2 yrs. I had registered for DND service in May 2008 with airtel. But I still recive these unwanted calls from variious companies like banks, insurance, travel agencies etc etc. Inspite of 3 reminders to airtel they have still not been able to solve my problem, the executives promise each time hat within next 24hrs these calls would stop but they have been unsuccessful...
