ESET security

I have been with ESET for many years and because my credit card expired and i had to get a new one, ESET sent my details to the bank and ofcourse the bank declined it because i had received a new card with new details. I did contact ESET and told them my new details and they kept on submitting my old details and everytime they did that, the bank charged me R8.00 so R48.00 later, i have not CANCELLED my ESET with no effort from them to fix the problem........ not happy
