Oriental Bank Of Commerce — Charges taken for asking balance of account

Address:

Oriental bank of Commerce, Karamsad, Anand, Gujarat PIN - 388325

For tax purposes when i went to obc bank, karamsad branch, anand for asking balance in my wife account (Opened at morena, madhya pradesh), bank manager and other staff refused to tell the balance and asked me to bring a signed letter from my wife. When i brought the permission they told we are not able to tell balance from here, we have to mail that particular branch and ask for statement. For this you have to write an application for statement. After i had given the application they told they will deduct ~118 rupees for statement (Which i had never asked for, i asked for only balance to complete balance sheet for income ta purpose).
What is the advantage of having an nationalized bank which during lockdown period is unnecessarily deducting money and not able to tell the balance. I am a doctor by profession and recently got shifted here at karamsad so my wife also moved with me. Please do needful.
