I have been using hdfc bank account from last three years and have not faced any single type of issues from their side .Infact the kind of services they provide is extermely satisfactory. One point of time , I requires a new cheque book and just requested it from the internet banking option in the evening and the next day it reached to me in the morning.
Reminders and mails are given by them regularly regarding all the details and revert regarding any queiries are solved very fast .
Overall till now I have a very good experience with them.
