Gautam Buddh Nagar, Uttar Pradesh, 201308

Hi, i have salary account in hdfc 3 years back when i was working at that time. After that my company has changed our salary account to another bank & they provided other bank account. But still my hdfc account existed and getting negative minus balance... Every months bank has deducted 600 rs minus to my hdfc account.
The bank converts my salary account converted into savings account & charged monthly.. Without my permission how can the bank convert my salary account into savings account? Even they are not intimated verbally... According to rbi guidelines on savings account banks not charge even its negative balance.
I approached our near by branch, but they did not close my hdfc account.
So what is the action will take against this bank.

If my issue not been resolved within week timeline then will take a legal proceeding against respective bank.

Kindly help me out of this!
