Vodacom sends careless updates to credit bureau.

Today I opened my credit record and found out that my credit score has gone down dramatically. I realized that an update of arrears was made by Vodacom. I was surprised because the full debit amount of R1476.90 was done on the 17th of October 2022. The next debit order should come on the 15th of November 2022.

How is this even possible? How do they update arrears when full amounts have been paid? I made a call to Vodacom and they said my accounts are up to date. So why did they send wrong information to Experian? How must I get my previous score back? I have been extremely inconvenienced and I am ****ed off.
