ICICI Bank — Change in Statement date for credit card

Hi,

I am using ICICI credit card for last 2 years, there were few transactions which i had made during the month of February and had converted those in to an EMI scheme which is provided by the bank for which the bank has already charged me. As per the conditions i am supposed to pay the equated monthly installments every month which i have been doing so since past 2 months. Last month the bank suddenly changed the dates on which the credit card statement is generated without any notification to me, so as per the bank am supposed to pay two installments together this month which is very difficult for me, i have to suffer even though i have paid the bank the processing charges for the EMI scheme because of the changes made by the bank. I had called the customer care and spoke to the manager but they are saying they cant do anything about it..Please help me with the same. Complaint number - SR72336373
