Account Status Incorrect

Account still active on Credit Bureau whereas it was closed moths ago. The account was settled and it is still appearing on my credit bureau profile as still active and owing an amount monthly. Submitted a query online with Cell C more than a week ago and waiting to hear from Cell C.

Please change the status of my account from "active" to "settled or closed" on the credit bureau. Please send me a letter and statement confirming that this account has been closed and settled. Also please update the status of account number on the credit bureau.
