Bank Of Baroda — unprofessional behaviour

Address: Jaipur, Rajasthan, 302033

We contacted bank of baroda branch pratap nagar, jaipur 302033 to opening a current account for partnership firm but they refused to take submission form due to using seal of partnership firm made in round shape and told that it is not acceptable, we were not aware of that so we request them to provide the reason behind it, but instead of telling the genuine reason they said that it is not acceptable and they also do not know the reason and started to behave rudely for asking the reason.
even the manager of this branch was not aware of that why it is not acceptable.
I need to take action against these unprofessional n untrained staff so we do not face such issue in future.

awaiting for prompt n positive response. thanks
