I hold a home loan account at sbi. Loan is approved and disbursed in 2015-16 time frame. Am paying my emi ontime (Ecs anyways).
Original documents of registration of my home are with sbi only.
Now a week back i was charged inr 1000 /- saying - search report charges.
When i raised a complaint on their portal, branch manager called and said, this is a random check on the home loans to verify the documents legal status.

But bank already charged - 'document charges' when i requested the loans.
Why again? When you (Sbi) think you are at risk, its your pain to resolve it or hedge it.
You can't charge the customers for the verification that you do on my document that is still with you.

I need a refund and not just me, the process needs to be clarified by sbi and refund all customers.

Screen shot of the complaint details and charges by bank are attached.
