If you want to complain about a bank staff due to her misbehaviour, you can follow these steps:
1. **Gather evidence.** This could include the date, time, and location of the incident, as well as any specific details about what happened. If you have any witnesses, get their contact information.
2. **Write a formal complaint letter.** This letter should be addressed to the bank manager and should include all of the relevant information about the incident. Be sure to be polite but firm, and to state clearly what you would like the bank to do to resolve the issue.
3. **Submit your complaint letter to the bank manager.** You can do this in person, by mail, or by email. Be sure to keep a copy of the letter for your records.
4. **Follow up with the bank manager.** If you don't hear back from the bank manager within a reasonable amount of time, follow up with them to make sure that they have received your complaint and that they are taking action.
If you are not satisfied with the bank manager's response, you can escalate your complaint to the bank's regional office or to the banking ombudsman.
Here are some additional tips for complaining about a bank staff:
* Be specific and objective in your complaint. Avoid using emotional language or making personal attacks.
* Be clear about what you would like the bank to do to resolve the issue.
* Be polite but firm. Remember that you are a customer and that you have a right to be treated with respect.
* Keep a copy of all correspondence between you and the bank.
* If you are not satisfied with the bank's response, escalate your complaint to the next level.
It is important to note that you should not confront the bank staff member directly. This could make the situation worse and could even put you at risk. It is always best to complain to a manager or other authority figure.
I hope this helps.
