[Resolved]  ICICI Bank — credit card wrongly charged

ICICI credit card is charging heavily, I have 2 credit cards in ICICI bank, but I don't know that they are of different accounts, when called to customer care(CC) they said you can do the payment in any one of the cards, I have already registered one of my cards, so done the payment. After 15 days I got a new statement stating that you due is pending 564 with a penalty of 632. I was surprised how can the penalty is more than due amount. I called and said regarding the CC misguided regarding the payment, so I have done in another card of mine which is also ICICI. They said the account is different so we cannot do anything, so I have requested them to reduce fine as it is more than the due amount. There should be a limit in charging fine, max of 10 %. so please consider this request and ask them to refund my amount as there is a mistake from their end. Also, make sure to restrict fine based on % of the amount, not flat rates. please find the attachment and resolve the issue ASAP.
