Bank Of India — I am complaining about penalty imposed on my account

Address:

460447

Staff of boi bagdona branch is so careless.
Boi staff is forcing me to pay approximately 11000 as panelty.
But still bank is not clearing for what i should pay panelty. Boi manager is not giving print statement of account or any legal proof for over draw of money from my account. As my account is saving plus account ffd plus, not any jandhan account.
Then kindly convey me if i had over drawn money. I am ready to pay it. But only after legal proof.
