Complaint Details:
Dear Sir/Mam,

I have a HDFC Bank credit card from above one year and I clear all dues timely as per card statement, but in the month of September-2016 some discrepancy balance with me for Rs.500.00 only, but against 500/- HDFC bank charges us penalty for Rs. 1667.00. I am surprise that agst 500/- they charges Rs.1667.00

Kindly help me for reversal heavy charges by the Bank,
