Bharat Sanchar Nigam [BSNL] — sim block - [protected]

Address:

#143, Phase-IV Mohali, Mohali, Punjab

I lost my mobile handset along with my sim card at iscon temple chandigarh. My mobile no. Was [[protected]] and sim card no. Was[protected]. I want to block the sim card so that no one mis use it. But the bsnl officials say they require a copy of fir. Only for blocking a sim card, fir should not be insisted upon. I request the bsnl to block my sim immediately.
My temporary mobile no. Is [protected]
