State Bank Of India [SBI] — Original documents misplaced

Address:

Patna, Bihar, 800001

I had taken loan from sbi, bihar school examination board (bseb) branch, patna (branch code sbin0001215). loan is fully paid-up.
The branch has misplaced the original documents as lic bond, black cheques etc.
When i talked to the bseb branch manager mr santosh kumar, he said the documents are with racpc gandhi maidan branch. after talking to him, i contacted racpc, gandhi maidan. according to racpc, the documents are still with bseb branch.

My lic policy matured in july this year but could not receive the amount as the policy is assigned with sbi bseb branch.
