BSNL — New replaced Sim not activated

Address:

Pune, Maharashtra

My BSNL Sim Card No.[protected]Mb.No.[protected], Sunil [censored]ole) was lost on 4 Jan-2013.So i lodged FIR and replaced my sim card from BSNL office on 19 Feb 2013.

Since 19th Feb 2013, my new replaced sim card has not been activated yet.I am getting error as "Sim card registration failed" each time when i insert sim in my mobile phone.

I called BSNL customer care and lodged complain on 4 March 2013.Since then i am calling bsnl customer care daily and each time they are saying that problem will be solved within 24 Hrs, but still my sim card has not been activated yet.

Its my regular number and i am missing many important calls due to this.

Please help...
