False Credit Rating

Completely disappointed with Capitec's customer service, After 45 minutes on the phone, transferred between numerous departments they were still unable to resolve my query. My salary was paid in a day late because of a payroll system issue, so instead of my loan being collected on the 31st it was collected on the 1st , the next day I get a notification from Experian informing me my score has changed , I check and see that Capitec is now in "arrears" , I call Capitec's customer service wanting to know if they can do a manual update to the credit bureaus, which mind you I have done with my other credit provider. I was then told that I need to wait until the 1st of October for the automatic update to happen and it will then show I'm up to date. Clearly someone did not understand what I was trying to convey , instead as mentioned above I was put through to all different departments to no avail. My credit score is now down by 10 points from Above Average to Poor!!
