[Resolved]  Idea Cellular Postpaid Connection — regarding call barring password

Dear sir
I had brought a fly phone and having the Idea post paid connection I asked regarding the call barring password to both of them but both are passing the bug by saying that this is phone build service and the phone company is saying that this is operator provided service.

I dont know from where I can got that call abrring password.
Please help me to get it ASAP

Thanks in Advance
