Citibank India- Unpleasant banking and unpleasant interaction

Never can one have a really pleasant banking interaction with Citibank India staff as they are always so full of bad attitude, rigidity and insensitivity. In fact one can easily detect a tone of arrogance and impatience in their voice even when they are wrong. In short many I know including I have always had quite an unpleasant experience in dealing with Citibank staff where complaints are concerned. In the recent episode of the cheque where Citibank was responsible for the wrongful  deduction of an amount of Rs.3000 instead of Rs.300, they did not even have the courtesy to send a written apology for the inconvenience caused. Instead they took long to even solve the entire issue and when their senior staff member Jyotsna called it was merely to inform me that finally the amount had been credited to my account and not to really offer a sincere apology. From her impatient attitude and tone of voice, it was very evident that she was really not ready to offer a heartfelt apology or take my feedback seriously.
From a reputed bank like Citibank India, one would accept better but what one receives is thorough disappointment because they do not know how to talk well with customers. They lack the professionalism, tact and diplomacy that is so required in resolving issues with customers. Their way of complaint management is careless and atrocious.
 Citibank U.S.A staff is so helpful, sensitive and courteous. Then one wonders why Citibank India staff have such a bad attitude ! Citibank India needs to train their employees how to have professional interactions with consumers without offending the customers. They are really in need of a lot of training. HDFC bank is definitely better than Citibank as their regional managers too get involved when addressing escalated complaints and are very interactive with customers. It is mostly pleasant banking with HDFC bank. Of course there can be problems at every bank including HDFC but eventually someone hears you at HDFC unlike Citibank India where nobody is willing to even understand the customer's point of view. I did have an escalated complaint with HDFC a long time back but their seniors got involved in providing an effective resolution and even made it up to me as a customer for the inconvenience caused. Many years back Citibank India may have done the same but since 10-16 years somewhere it seems they are hiring the wrong sort of people who are definitely not able to perform well with customers or their training is lacking completely. Anyone who is a HDFC customer would never ever like any other bank because they assign a team of dedicated people to your account to make your banking experience as pleasant as possible. As I say there are all kind of unprofessional people everywhere and at every bank but Citibank India has most of them. My feedback is based on all the feedbacks I receive from other customers as well.
