Terrible service at Standard Bank

I have settled my credit card on the 16th of November and requested that the account must be closed. I also settled a Nedbank account on the same day. 7 days later the Nedbank account was removed from my ITC but not Standard Bank. I have made numerous calls sent numerous emails but no one seems to take responsibility for informing the credit bureau that the account is closed... everytime it is the same story they ask me to send an email and they will follow up. This is totally unacceptable as they are quick to list you as a slow payer or defaulter. I need action taken immediately it cannot take someone 60 days to inform them that an account is paid up and closed!!!!!
