BSNL — Can not Receive Calls

I have Ported my BSNL number ([protected]) to Reliance and the portability was successful, now I am a Reliance Customer, But I cant recieve a single call from BSNL. When ever my BSNL friends or Customers try to call me it says the number doesnot exist. But
On the otherhand I can call those numbers.... when I asked about this to the reliance customer care they said it was not their "head ache" it was the other service providers ( BSNL ) problem,

But being at the consumer and I am facing the problem because I cannot go to each service provider and ask them to register my number.

So pls look into this matter with an urgent basis and solve my problem as early as possible.
