ICICIcredit Card — PURPOSELY CHANGING THE PAYMENT DUE DATE TO CHARGE LATE PAYMENT CHARGES ON ME

Sir, I have purchased icici credit card and using it since 06/2004.At that time my payment due date was fixed as 1st or 2nd of the month. As a government employee it was convenient to pay the minimum amount due.but now they have puposely changed the payment due date so as to charge late payment fee.ie, they unanimously fixed 28th or 29th as due date.it is an injustice to all salarried class people.moreover they are indirectly sucking my money in terms of rules framed by themselfs.please stop this cheating nonsense people sucking our hardearned money (blood)
