I opened my account in Citibank in 2005 and I am very satisfied with the service they provided during this period, most of my banking work I do using mobile and net-banking and I hardly need to visit in any citibank branch, but If you live in Delhi and do business in cash then Citibank is not for you because there are very few branches of Citibank in Delhi.
Recently they announced that minimum balance should be 2 lac for new customers and 1 lac for those who are already their customers for long time. If you have 1 lac, just make a FD of it and forget it for few years so your minimum balance will count as 1 lac and continue enjoy their best Net and Mobile banking service. I also have accounts in HDFC, ICICI and Bank of India but no bank comes near to Citi net and mobile banking, 95% problems you can solve using net and mobile, and for 5% you will have to visit any branch.
In last 8 years I have visited only 9-10 times in Citibank branch mostly to deposit cash. You can visit Vasant Kunj branch near Priya PVR cinema till 6 pm.
