i had SBI credit card some months back and i used it for some purchase , i had repaid this amount at right time

Now i had cancelled SBI card ,but now also SBI used to send me the credit card statement mentioning i have to pay the insurance charge of the card.
I had not applied any insurance for the card ,and SBI is claiming that i had to pay the amount even after closing the card.

I had even complainted this to SBI ,but still am getting the statement montly.

Request to take strict action about this and stop this kind of intellect faruds.
