ICICI Bank — Credit Card Closure Request long ago

Hi team, My name is B Baldev Singh. I am having a credit card with your bank since long time. As i am unable to pay the interest i thought of closing the credit card. I requested the closure of credit card but costumer care girl said me to pay off the outstanding the amount and hence my request will be accepted. As accordingly i paid the same and requested for the closure. But when i called again they said this number and my email id [protected]@gmail.com is not in their records or it is not matching with the credit card. This is the problem i am facing with the team since 2019 and they have been putting the late payment fee every month till now. The customer care said me that if the payment is done at that moment there will no dues again and i can proceed with the closure . But till now they are charging me with late fees. I kindly request you to help me with closing this issue at the earliest as i am really feeling tortured and mentally harassed with this thing. If this thing isn't resolved i will surely file a case against icici for misguiding and cheating . So it my request to you please respond accordingly at the earliest.
