Similar thing happened to me couple of months before. I called customer
support, when i didn't proper resonse & attention, i blasted them over the
phone (politely) & threatened that i'll cancel my credit card (I'm using
ICICI credit card since last 5 years). Immediately they reverted back that
amount with an apology note.

I hope that will work with you too. Because of competition in the market,
credit card companies/banks don't bear the loss of existing customer.

Good luck

Hey frnd

welcome to our forum, i have complete knowledge of your complaint, let me just tell how it all works, if i am getting you right you made double payment by mistake, one by cheque and one online, and after that you gave them instruction to stop payment.. sir i would like to tell you whenever you put a check to other bank for payment, the other bank pays certain amount to your bank to get that cheque cashed, and the penalty they are charging you is of that amount, even if you have called them and canceled the transaction but still its ICICI bank, a big bank with lots of business daily so they must have already contacted you bank for cashing it..

I will suggest you to write to them and dispute the cherge they put on you, i am sure that if possible they will revert back the amount, otherwise you need to pay the penalty because what they did is absolutely as per banking policies, every other bank will do the same if u put a stop payment on cheque, read the instruction they sent you at the the time you got credit card...
