Credit card account closure

I have sent an email to FNB Card division on the 13th of December. It is almost a month later and still no response. I paid up my credit card in August 2021. It was confirmed in October that the account was closed however, this account is still showing on my credit profile. Everytime I send an email, they ignore me for at least a month ND then I have to resort to Hellopeter with a complaint.
