ONE CREDIT CARD BUT LISTED TWICE ON ITC CR BUREAU

I have access to my credit profile on ITC Transunion. I check this regularly because of continual duplications and incorrect information being given to the Credit Bureaus. I sent an email to the credit card division when I noticed that my credit card with Standard Bank appears twice against my name. The same thing happened to my wife last month. I have not heard anything back from them and I need to have this rectified soonest. It is negatively affecting my credit profile and the details sent to the credit bureau has been incorrectly sent by Standard Bank to ITC Transunion. I want this removed immediately.
