I have corporate account with HDFC bank and I have been living outside of India over 2 years. As I do not get salary, I have minimum balance.
When I took the account, it is told it is zero balance account because it is opened through company. I opted this bank over others because it is zero balance account.
Without letting me inform they started changing me total 950 rs per Quarter as debit card free.
Be careful about this HDFC bank hidden charges and prefer government banks like State bank of India.
