State Bank Of India [SBI] — property insurance

Address:

560103

I have taken a home loan from sbi, kormangala branch.
Loan has been disbursed. But then, they have forcefully added a property insurance one time premium of around 70, 000 thousand rupees to the total loan sanctioned amount.

Also they didn't mention this property insurance thing upfront. Once i filled the loan documents, they pitched this property insurance as life insurance cover and later only i came to know that it's a property isurance not life insurance.
I had spoken to the branch manager, but then of no help.

Now i need help of how i can make the bank to remove this property insurance from my home loan account.

My sbi loan account no - [protected]

-thanks,
