Citibank — Lousy customer service

Address:

Chennai, Tamil Nadu

I have been using Citibank card in Chennai india for more than 10 years.. inspite of being their prompt customer the customer service people are not responding.. I have submitted my KYC more than 10 times they still haven't updated their records.. each day I call them and am put on hold for 30 mts only to be promised of a action and no nobody calls back or does the needful Am going to file a suit and this is the worst bloody bank I have seen .. a cost I pay for being prompt in my payments...
