Absa Bank - no customer service - "Africanacity"

I have had a personal loan with Absa for more than 1 year. For the past 3 months they have been sending incorrect information to the credit bureaus. My account is paid via debit order and never once in arrears, however on Transunion it is 90 days in arrears, on Experian 1 month in arrears. I send them an email trying to get the correct information and I get an automated response telling me my query was resolved. This has impacted my credit profile and I could not get car finance.
