Account paid in full, yet you blacklist me??

Dear Standard Bank Vehicle Finance,<br> <br> My wife obtained financing for her vehicle through your organization. On 11/10/2014 she received a letter stating that the account had been paid in full. She followed the process and had the car registered in her name. All payments were done via debit order.<br> We are now in the process of buying a house. A credit check conducted by Experian revealed that an amount was outstanding and that our credit rating was affected, resulting in a \C"rating instead of \""A\"". A call to the call centre revealed that there was no amount outstanding. Yet we are still somehow listed as a bad payer"
