When we use phonebanking facility, it is call center and we have to interect with machine by wasting our valuable time and then some executive will come over the phone (which changes ever time) and many a times they do not have proper updates about the products of the Bank. Further to addition they do not owe any responsibility towards customer. When we ask them about their seniors they keep mum and avoid the answer. I personnaly do not prefer to have account with Bank who are talking through machine rather it is better to human face for your problem.
So the nationalise Banks are perferred over and above over the issue. Atleast they are having human face to solve the queries.
