Bluebean/Standard Bank Credit Card incorrect negative listing

I had a Blue bean card from 2006 and paid it up in December 2016. I recently tried to apply for property and I was informed that I am in 8 months arrears with my Blue Bean credit card payments. I had to check all bureaus to confirm which one has that negative listing and I discovered it was Compuscan. I logged a dispute with Standard Bank in early Nov 2018 and I was informed that it will be updated on the 30 Nov 2018. I also logged a dispute withe Compuscan which is awaiting confirmation from Standard Bank to enable them to update my profile, it's now a month and nothing has been done. This is affecting negatively and derails my plans altogether. May you kindly prioritize this request as I have gone through all the necessary processes at Standard Bank but I still did not get help.
