ICICI Bank is India`s oldest and largest bank. I am an 8 year old customer of icici bank. these are also providing good service to their customers such as: SMS banking, NET banking, ATM & loan facility etc. This is the best customer service of the bank. this bank opens its account within an hour. the specialty of this bank is that its services are very fast and now the bank`s typing bank is also from paytm bank. this is a great bank and I suggest you open this bank account too.
