Bharat Sanchar Nigam [BSNL] — phone blocked... requires puk code

My bsnl no is [protected]and it was bought around 8-10 years back. It has gotten blocked and for unblocking, it is asking for the puk code.

I tried getting by sms number provided in the online forums and also other methods but have not not received any details yet.

Unfortunately we do not have much idea on the address and name under which the simple was submitted as it was taken almost 10 years back.

Kindly send us the puk code to unblock it
