Updating ma Credit profile

I am livid , I settled my revolving loan with Standard Bank only to find out my Trans union credit profile wasn't updated properly (It shows that the account hasn't been paid in 30 days). I call their billing or loans call center only to be told its because the account is still active , which doesn't make sense to me because either way a payment was made.When I paid up I instructed the lady at the call center that I am closing it and I don't understand how it wasn't done.When I call back the guy who answers doesn't even seem bothered by my problem and is referring me to Customer Care if I have a problem.Its not on .I am ****ed.
