ABSA failing to update my payment history on credit bureau

I took out a loan with ABSA 3 months ago and have been paying my monthly installment as per my commitment with the bank. However, on my credit profile, the loan is reflecting as arrears and this is very frustrating. I contacted the collections department a few weeks ago and was told that this matter will be taken further and changed on the credit bureau but this issue has still not been resolved to date. I am really disappointed with the service and lack of customer care that i've received from absa regarding my loan as this has a negative impact on my credit score already and i cannot obtain any other credit elsewhere up until this issue is resolved.
