Incorrect credit bureau information

Standard Bank has provided the credit bureau with incorrect info regarding my Revolving Credit Plan. My account is in perfect order, yet my credit report shows my account going from good order in October to suddenly 5 months in arrears in November! Not only is this incorrect, but physically impossible as it cannot suddenly jump to 5 months overnight! I have confirmed with the bank that my account is in good order and that they will notify the bureau, but apparently this will take two weeks to do! This is unacceptable. This is adversely affecting my credit rating and preventing me from applying for credit elsewhere. This is an error on the Bank's part and should be corrected immediately! I should not be forced to wait weeks for the bank to correct it's own error!
