[Resolved]  ICICI Bank — Wrongly charged Auto Debit fee on Credit card

Address:

Mumbai

The bill generated for the month of June on my Credit card was Rs 9006, I received some refund amount Rs 2130 from a merchant. So my total Outstanding amount on Credit card was Rs 6876. Based on this Outstanding amount I paid the bill of this same amount (Rs 6876) before the end of billing cycle (on time payment).
Now I have been charged with Rs 531, ICICI bank representative is saying since I have paid only Rs 6876 I have been charged for this. I should have paid Rs 9006.
I believe I have been charged wrongly for this amount Rs 531 as I have paid the Outstanding amount charged on my Credit card before time. I have always paid the bill on time.
ICICI bank should negate this charged amount.
