How can you do like this? I have never used this facility and not interested to use at all. Please credit the same amount in my account as early as possible.
Otherwise i will make complaint to rbi. If you will keep on donig this we will not use your bank facilities. Will stop all transactions henceforth.
Your bank is not keeping our record confidential. So our credit card information has gone to one assist company.
