You bank. Review on HDFC Bank

I am having HDFC bank account previously it was salary account but I had left my organisation in march month after that is become as a normal savings account so my issues regarding for I've got a charge for non maintenance balance. I was working in intelenet global service till March even my fnf processor was not done from that time today itself I've got a charge for non maintenance balance I spoke to my RM regarding for this problem. But she said that is correct and that charges is not refundable very worst services HDFC offer even I have not got any kind of update regarding for that I am getting charged for non maintenance balance suddenly they put it that charges in my account 10000 rupees in negative balance now they are saying that you have to pay that charges otherwise knows that bank account when he was thing about that. I recommend you if in your organisation if we having a option for salary account do not go for HDFC after left in your organisation you will be facing a some trouble regarding from that I'm sure about it.
