I have also a savings account in United Bank of India. After many years experience with united bank of india, I think it is one of worst bank in India. Many of bank staff works very slowly. Their behaviour with customer is very bad, specially if they are poor. Sometime I noticed that the many of old staff are seems like uneducated. They do not understand english, they do not know how to operate a computer.
But some of bank staffs work very nice and their behaviour is good, but it is very less in number.
So, overall it is one of the worst bank in India.
