HDFC Bank — HDFC Bank NWD DEC CHG - Amount Deducted

An amount of Rs. 29.50 has been deducted from my account with the description NWD DEC CHG, even though my account was opened as a salary account and it was said that there will be no surcharges for any no of withdrawals from ATMs other than HDFC. There were no intimation regarding the policy change (if any) also. I think this is very bad and unprofessional on the of HDFC Bank.
