Settled account still on credit bureau's statement

In march all my accounts was settled by debt busters. I have to accounts by absa and the vehicle account was sorted out three times before I had to get it sorted by writing a report on hello peter. My credit card account was also settled and the paid up letter was with the vehicles paid up letter sent to absa on the third try to fix the problem. Now the vehicle account is closed but still not the credit card account. I cant upgrade my phone to a tablet because of that still showing on my credit record. I did ask in the beginning of may when I phoned about the vehicle account that they would also do the credit card account but it didn't happen. I did send a mail again Monday(6 days)ago and still no response.
