Indian Overseas Bank — Employee rude behavior

Address:

IOB govindpura branch

My account is in IOB as savings account in govindpura branch, bhopal. My maid was getting a savings account open and coincidently i reached there to get my pan card linked with my account.
The way that employee was talking to the maid was so rude and not at all helpful. Employee was using words like overwrite, original copy and acknowledgement form. My maid was not understanding and was panicking. To which i told the employee to explain her in a way she can understand. I even told the employee that she lacks financial awareness. To which the employee told me you do your work and not interfere. WHY SHOULD I NOT RAISE MY VOICE against such behavior. They even asked my maid the salary she earns while working. To which the other employee said raise the salary of your maid and that is how you can help! THAT'S MY PERSONAL MATTER. what we pay to her. They say there are a lot of employees who come to them. SO? It's there job to make the customers aware about products and services rather behaving rudely.
