Wrongful Default listing on Credit Bureau

I had a revolving loan with Standard Bank opened in 2011 which was settled in 2014 and account closed subsequently. However upon checking on my credit profile report last month it showed that the account is active and I am in arrears . On the 26th October 2017 I had then made contact with Standard Bank informing them of the error and was advised that the query was logged and my profile will be updated in few days. Following week I then made a follow up and same thing information was relayed to me and that my profile will be updated accordingly and that it was a matter of 3 days for the credit bureau to have this updated. However today Monday the 13th November 2017 a couple of weeks later nothing has been done as I checked my credit profile again and it still reflecting that I have an active revolving loan with them that is in arrears. Besides being told several times that this was being dealt with and the matter will be resolved.Upon seeing this I then called Standard Bank to be told that on the system they cannot see that I had a revolving loan with them. Even with my ID and the account number reflecting on the credit bureau they are unable to pick up that specific account however what baffles me is that they were able to contact credit bureau and list me as a defaulting customer whilst they cannot not even locate that specific account thatI am supposed to be owing and not paying. I explained to them that my life has literally stopped and at a standstill because I am unable to do anything because of that wrongful listing and that this needs to be sorted today. I am literally at mercy of Standard Bank because of this and it is affecting my life negatively as I am unable to do anything but I am being told that this will not be resolved today as my per my request since I have waited weeks now whilst someone was lying to me about this being resolved while the truth is they cannot even locate the account on the system. I am so frustrated right now and Standard Bank is not taking accountability to make sure that this matter is expedited and resolved as a matter of urgency. Nobody has even apologised and I am told I need to wait. Question is how long do I have to wait for something that was wrongfully listed under my profile. This is highly unacceptable . I am angry that I have a wrongful listing on my profile and that I was **** to and promised this would have been resolved by now but to date nothing. Beyond frustrated !!!!
