Accounts paid in full by my ITC not updated

I have send an e-mail on the 20 April 2018 to log a dispute against Dumani & Bruma Finance as these accounts was paid in full. I also attached the paid up letters. Till to date I have not receive any feedback in regards to this as well a new credit report stating that is removed from my name. This is really pathetic as it stats in our South African law that if a account has been paid up or prescribed that your name must be removed from the ITC immediately. So in other words these ITC companies think they are above and beyond the law to do as they please. Both of the creditors informed them as well that they must remove my name from the ITC but they did not. I phoned them today, 22 May 2018 only to get this answer, oh sorry sir I see that the email was send on the 20 April, the other department says that your status will be updated maybe tomorrow. This is really pathetic. I want proof thereof today, 22 May 2018 as I am waiting now a month and 2 days. I am not waiting any longer.
