Credit card not canceled for 4 months

I have instructed WFS to close my credit card in May 2022 as I paid up the outstanding balance. Since then I have send 16 emails to close the account. NO RESPONSE! 3 Months later, it is not resolved or closed. I have send many emails and a senior manager would have contacted me at the beginning of August. In the interim the card has been charged with monthly fees and now there's a balance outstanding. WFS staff members don't care about service at all. I have already told as many people as I can about woolworths service. I am fedup sending emails and only recieve noreply emails. Even the MANAGEMENT OF WOOLWORTHS do not care or understand SERVICE!!!!!
